My level has been reset to 1
My level has been reset to 1. All my progress has suddnly disappeared and I cannot get away from beginner's screen. What's happened?
You're still level 11 in Italian.
But since you're writing here on the "Troubleshooting in French" forum, it seems you have switched your account under the French interface of Duolingo where you see only courses and levels for courses "from French" (like "Italian for French speakers").
