I've been playing this game for years on my phone. Invested lots of time in this just to all be wasted. Downloaded the November 2021 update and no longer able to play on my galaxy s21 ultra. I've tried everything from deleting the game,updating software, to restarting my phone etc. I've sent messages to the developer and to Google. Just to get a we can't help you response. Unfortunate they have lost a dedicated player to this game.
