Language settings reset everday

Hi, I log in from Germany but until now always had the English language setting. Since the "rapid" update, lichess starts off in German. If I switch back to english it stays for a day, next day the same thing.

Also selected Germany as my Profile location.
Thanks

See lichess.org/forum/lichess-feedback/problem-with-language-picker which is possibly related. The mobile app sets the global language variable (used both on mobile and web app) to the phone language setting for lichess on startup.
