Wrong answers marked as correct
Is there a way to report those? And Duolingo's mistakes? For example, when I'm supposed to choose correct translations of a phrase and I lose a heart, because according to Duolingo a grammatically wrong answer should also get marked? It's rather common in the French course.
There is no "Still think you are right?" option on multiple choice questions. So use the "Feedback" tab on the far left of your screen.
