Can't reply to comments on Duolingo app (Android)

So whenever I try to reply to someone's comment on the app, instead of the comment previewing while I type my reply, it shows a bunch of numbers instead. Then when i hit submit, it says "An error occurred, please try again later." I'm not sure what caused this but I used to be able to reply to comments in the app before. Any ideas? thanks!

Known bug (see here and comments there).

I suggest you fill a "Bug Report" form (with as much details as you can, cf. text in this form), those forms being read by staff. While they will not answer to it (well, up to some exceptions probably ;) ), because they can't answer to each one, they nevertheless use them (among other criterias) to prioritize their list of bugs to be fixed according to the number of Bug Report forms received for each bug.


Had the same issue, did all recommended actions to fix but none worked so just waited until next day and it is working well.

    I have the same issue. Very frustrating


    Same problem (after two updates), and it seems as though it happens with every course.

    I do Duo on a phone, but also usually have a tablet handy. So my workaround is to post a new comment on the phone (it accepts those OK - just not replies to other people's comments). Then on the tablet app I go to "See whole page", click on "Activity", click on my last comment, and then I get the full editable comments page. Now I can copy and paste (and delete) my comment from the main thread into the replies thread for the specific comment I'm replying to. It's a bit of a hassle, but I often go to this page to edit my comments anyway, so am used to it..


    I have the same problem. Can't reply to any comments.


    Restart your app?


    Not sure if you meant to force quit the app, or reinstall it, neither of which have worked for me.


    I have the same problem. I've never been able to reply to comments since I first started using duo in about 5 months ago.


    Seems this is now solved, but other bugs have appeared...

    The developers are destroying the android app. It cannot be launched easily now.


    Hey! It's been fixed now. \o/
