Multiple courses in iOS app
I am a foreigner living in the German-speaking part of Switzerland. I use Duolingo to learn German from English during my daily train commute.
This being Switzerland, lots of my coworkers speak French (some being French). I then thought it would be fun to start the French course… From German. Bad idea.
The iOS app simply lost my German course. I thought it was lost forever, but when I added it back all my skills were there. But then the French from German was gone, and I was presented with French from English. Afraid of more bugs, I deleted it.
