This app was great, but now it won't load. After the splash screen, I get a blue screen with a white rectangle in the middle, and a small light blue rectangle beneath it. Then it is unresponsive. Restarting app and tablet doesn't help. I'm on a galaxy tab S6, Android 11. Just bought our son Bowsers castle for his 5th birthday. He still hasn't been able to play with it properly.
