The game is crashing more and more frequently

The game only crashed once in a while in the morning, but in the evening it started crashing a lot more. Worst of all, before the crashes, green squares started to cover my screen. Is it an issue on my end, or did they fuck up the game during the update?

Here’s hoping my iPhone 11 can run the game smoothly

It ran the Big 3 Hoyo games(Genshin, HSR and ZZZ) fine, but it was disastrous for Wuwa. I can only pray the latter’s problems won’t happen to me when this game comes out.
