Android app needs reporting facility
I like the new "look" of the Android app, but I am disappointed that there is still no reporting facility and there are (on the French course, at least) LOADS of: 1. Incorrect answers, 2. Examples where a correct answer is rejected, 3. Incorrect Dictionary hints 4. Examples where a dictionary hint is rejected as a correct answer.
Come on Duolingo, it is very demoralising if you constantly run out of hearts because of errors in the system!
