Error in training 3
In letters3, lesson 1/3 i cannot go on because of the course gives the last answer as fault. But there is just 1 possibility remaining and that should be good. I cannot go on with the training.
Other problem is trying to.report as a bug I cannot add screenshot or send message in Android. Getting bit annoyed by this app now.
I have seen quite a few users having the same problem on the app for some lessons in the Letters section and I believe a fix is still in the works. You can report the bug here with screenshots.
Until its resolved, I think the only workaround is to clear the problematic lessons on the web version. You can also use duolingo.com on your phone's browser to clear them.
