  1. I’ve enjoyed Duolingo for several months and have learned a lot, however recently when I have to choose a multiple choice, the boxes where the choices are displayed, are no longer visible. Just 6 blank boxes which means you have to guess blindly which results in you getting the wrong answer, unless your lucky. It’s so frustrating because I know the right answers when conjugating a verb.
    Please fix it because I truly enjoy and learn a lot with Duolingo. Merci!

    • I am on a 640 day streak, I play duolingo on my iPad but I’m unable to access it because I keep getting a message when I try to open and it’s saying your duolingo is out of date update to unlock the latest features, when I press for update it takes me to the App Store, I press the update button and it just takes me back to the message, Please can you help me I don’t want to lose my 640 day streak, but think I’m going to have to delete duolingo and start again.

    I had progressed a long way (21000 + points) through a french course. Tried to continue today only to find I had lost the course and was fed a lot of unwanted stuff that required that I restart from the begining. Aw! C’mon.???

  3. Please do not send me warnings with exclamation points that I am about to lose my streak if I haven’t finished my lesson by 10 pm. “You are about to lose your streak!!” I find this kind of messaging to be an abuse of the communication access I have given you. You have no idea what can happen in a person’s daily life. While I don’t mind being reminded to complete my lesson, receiving this kind of exclamatory message is offensive. The idea of sending it every evening if I haven’t finished by 10 pm is appalling. People come home from car accidents, a work crisis, a family sorrow to find some application is sending them alarming messages about their ‘streak’. Please do not send me this message again.

  4. I am rather shocked that you do not include Arabic as a language! Though I was pleased to see Irish as well as Spanish and German. But why no Arabic? Someone else was shocked that you didn’t offer Tagalog.

  5. I recently updated my tablet , hence Duolingo as well. I do not like the new, “losing health”and feeling pressured to purchase unlimited or feel stupid for your mistakes. I prefer to keep trying until I learn something without pressure.

  6. Duolingo enforces translations that are too specific, and it is too clear their teachers and graders can’t speak English and they can’t always speak the language they are teaching either.

    Their French course is full of problems. For example.

    “Ma tante n’a plus de lait”. I translated it, “My aunt does not have more milk”. It was marked wrong. I had to say “My aunt is out of milk”. These are two valid English ways to say exactly the same thing. There is a lengthy forum discussion about different possible permutations on translating that sentence, most participants in which clearly don’t understand English worse than they don’t understand French. A few people said stuff like, “Why can’t you say my aunt is out of milk”.

    “Il ne peut plus marcher. I put “He can not walk more”. Duolingo marked it off, and said the correct answer is, “He can not walk ANYMORE”. Anymore is not even an English word. “He can not walk more” and “He can not walk any more” are the same statement.

    There was a lengthy forum discussion among people who clearly don’t know ENGLISH about various conceivable permutations of that sentence. Obviously Duolingo’s enforced wrong answer has been debated for a long time.

    Another, and proving this is no fluke: “Le garcon ne peut plus lire”. I put, “The boy can not read more”. Duolingo marked that off and said the correct answer is “The boy cannot read ANYMORE”. Again, a long debate on the forum among people who clearly aren’t native speakers of English and don’t know how to speak it.

    Then I decided to try Duolingo’s version of the correct answer, but in correct English. “Je ne sais plus”. I put, “I do not know any more”. Duolingo said, “You have an extra space. I do not know ANYMORE”. Again, a long debate about it on the forum.

    This is just one set of examples of the same thing; Every subject area at Duolingo it’s something like this.

    And here is how they pronounce “nous avons” at Duolingo. “ju avon”. The correct pronunciation is “Nus avon”. The teachers of the course do not know that usually the final consonant is pronounced if the next word starts with a vowel; they state that the final consonant is never pronounced. I researched it; the s would be pronounced in every major dialect of French. AND the “ju” is coming from the fact that Duolingo’s French teachers are native speakers of the Chilean dialect of Spanish. Weak consonants just become j or ch. Their speech is often impossible to understand in the French course!

    The problem occurs far less often with their Spanish course, because they’re native speakers of Spanish and they know what they’re talking about.

    It would be very helpful if the ‘words’ section was arranged alphabetically rather than by date used. It is impossible to find a word quickly.

    I can no longer get into free Duolingo to practice. This started yesterday. I get to the point of selecting something like food, the wheel starts thinking and then everything disappears. Is there a set number of hours for free or what is going on???

    I am not happy with the Italian Duolingo. After almost a year, I have not learned many useful phrases. Instead I learn “he hurts himself with a knife” and ” but I am a married woman ” and “you unite the workers” . There are many stupid sentences as well as sentences about hurting animals, boyfriend/girlfriend issues and communist propaganda. My sister is learning Spanish on Duolingo and told me how she is learning so much useful travel phrases. She has learned none of the bizarre things I am in Italian. She can make reservations, order food, and other helpful things in Spanish. I have not learned these things after almost a year in Italian!

  11. I want to change my email address and when I go to settings it is greyed out and it will not allow me to change it. how do I change the email address?

  12. I am using the russian and spanish apps. No problem with the russian app but I cannot move above section one in any of the spanish lessons without having to pay 400 gems. Plus I receive no gems for completing a lesson. How do I resolve these problems?. I would like to move further in Spanish but I cannot.

I have t been able to play since yesterday and now it’s stuck. How can I change to an hour, be put where I should after my test, and speak French which has been my aim?

    I have used The German programme for a couple of years, but now you have changed the programme and I find it very poor. If you have only have little time during the day and you make several mistake it is not available for several hours or you pay for it to to tinue which is out for me.
    Please reinstate the old way to give the slow learners a chance.
    Thank you for your help.

    I’m doing my lessons and the (cancel/quit) keeps coming up to drive me crazy. Or I press the chest for reward and all three open at once with Come back tomorrow Very frustrating. Do you ever fix these bugs?

  16. I lost my ability to open Duolingo after a Windows 10 update. I cannot remember my username or password.

    I have complete the form for “forgotten password, We will send you instructions on how to reset your password by email”, and received the message “Please check your email”. Unfortunately, after trying many times, I have still not received the email.
    Please help!

  17. I lost my streak as I was offline, however, I had downloaded lessons and had completed these whilst off-line. These should be synched back when i came back on-line and the streak should not have been stopped. I would like the streak re-set please.

    There are quite a few mistakes in the Turkish language site. Because of that I lost points because no health erroneously was left. Cannot get to the other languages then either. My opinion: stupid system!

  19. Hello
    I have been using duo lingo for the last 5-6 months.
    Last week when I was working on the sections time and occupations the whole thing froze. When I went back in 2 days later the app wanted me to start at the beginning. I have passed the first check point but cannot go any further it won’t even let me redo what I have already done as it wants me to sign up for a profile which I cannot do because you already recognise my email and the app will not use it.
    The programme is good and I want to continue from where I left off. I had over 950 gems but this was changed to 500.
    Have you changed the structure of the app? If so it would have been good to be forewarned. Your help would be appreciated

    • The same thing has happened to me. After using Duolingo to learn French for a number of months, Duolingo is now looking to create a profile and won’t accept my email address as it already recognises it.

      I would really appreciate learning how to fix this issue.

    I have been, I believe on your top level of Spanish for 4 months or more but it stays at 65% no matter what. Is this the maximum potential for your software or is this a program bug? Iam using the paid version.

  21. Please can you help me figure out how to change the language on my home page. It used to be English but I accidentally changed it to some Arabic language. There is no drop down menu by my avatar to change it back to English. Have even considered cancelling my account but because the language is indecipherable I can’t even do that.

  22. Good morning- I am using the free version of Duolingo to learn Danish.I started about 9-10 months ago on my computer but switched to my ipad 8-9 months ago as I could practice in the car or out of town.This time , for the first time I was asked to sign in on the ipad and when the app opened it read that I had just completed Basic 1 at 15 pc Danish. I am on a 74 day run and had started Attributes, close to completion. You have stopped my run, (this is not about points but about a daily routine)and the ability to continue learning Danish. I don’t care about points,adverts, what ever. I started something and I want to complete it and have invested 9 months. Please get back to me and let me know what you are going to do about it. When can I continue because I am not going back to Basic 1.
    Jon
