That sucks, I also play on my phone and typically find whenever my game keeps crashing I should probably restart the phone lol. But I'm on a Galaxy S22 Ultra, so unsure how this factors for other mobile users.
If you haven't already, make sure you are updated to the recent version of the game as well. There may be a fix if you aren't (I recently realized I was like 3 versions behinds... like 22 or 23, not counting the .2a or w/e extra lmao)
