Why Disapear Languages on my profile?
I did finished German some weeks ago, and started English then I noticed My german is gone!! Help!! Does someona has the same problem?
Duolingo only shows languages that share the same initial language. Say, for example, that you learn Portuguese and French starting from Spanish...but later on you switch to start learning Italian starting from English. Duolingo can only show your progress in either French + Portuguese OR Italian. You can switch back to the other language, in your case German by 'adding a new language', it will give you back your progress.
I hope this helps you.
