Hi, I waited several minutes but nothing happened. At first I thought it might be due to lack of disk space but I still have more than 8GB left, seems enough to me.
Anyway I decided to install the app on my PC and there it works as a charm.
The app doesn't work on my phone (Nokia 6.1, Android 10). I only get the startup screen. No music, no buttons, nothing's moving, just the startup screen. I uninstalled the game, installed it again, same result.
