Noticed this the last few weeks now, so really hope something can be fixed. I have an iPhone, every time I try to swipe up to close the game, more often than not it freezes and I have to click the side lock button to turn off the screen. It lags my phone and the game is frozen on my screen for a while before it will turn off black. When I unlock my phone back up that’s when the screen on the game will flash multicoloured.
Not sure what the issue is but please look into this 🥲
