Incorrect Correct Answers on Android
Duo in Android has been doing this kind of thing to me recently:
This is a problem that has existed on the iOS app since it was updated so it looks like it is also on the Android app as well. When you get something wrong, it shows you what you wrote instead of what the correct answer was. This looks like French so I cannot help any further and as the original question is audio it is difficult to know what was said. Hopefully you will get an answer from a moderator as it is frustrating.
