I have created a web app(PWA) for my game. The web app is created using Ionic 4 and game is created using Lime JS game framework. The game loads in an Iframe inside the app. Now earlier back in IOS 12 the game was running fine but after updating it to IOS 15 I have noticed that when I load the game in Iframe and change the orientation of the phone or move to another app and then come back to it the game screen becomes black. I am certain it has to do something with the update but not sure how to debug the issue. I have tried removing the CSS but so far I have not been able to figure out the issue. Has Anyone else faced this sort of issue before? Thanks
