Blank black screen

2025-12-23

by Hevdidknsdv

I can’t open the app anymore. It’s just a blank black screen when I try. Very frustrating because my daughter goes to German school, I’m not a native speaker, and this is often the only way I know what’s going on at school. Now I’m in the dark and can’t figure out a way to fix it. I’ve tried everything.
