Our WebGL games made by Unity encountered serious problem in iOS 16.7 and 17. Some game players have reported that the game is stuck. The log is related to "WebGL: context lost", which only appears in iOS 16.7 and 17, and does not occur in lower versions. It seems that if you open the game in iOS Safari, switch to the background for a few minutes and then come back again, the problem will reappear with a certain probability.

After investigation, it was found that not only our games, but other game manufacturers also encountered similar problems(Here is similar feedback from other manufacturers:https://developer.apple.com/forums/thread/737042). 

Moreover, games produced by other game engines such as cocos have also encountered similar problem.

Please let us know if this still reproduces in iOS 17.1 Beta 2.
