I develop games on my M1 Mac Mini using Unity. I then export the build right there into Xcode, and later to App Store Connect.
DESCRIPTION OF PROBLEM: I have an issue with a few of my newest builds on TestFlight and now on the App Store. This issue only happens on certain devices. While playing the build in TestFlight (and now the App Store) on an iPad (I will call this iPad 1), the screen bloomed drastically on certain scenes. On the other hand, on a different iPad (I will call this iPad 2) with a different Apple ID, the game was completely fine when it played the build on TestFlight and now on the App Store. Also, when testing on an iPhone which has the same Apple ID as iPad 2, the build on the iPhone blooms unlike the iPad, concluding that this is not an Apple ID issue. This App is made with Unity, and I tried to trace the issue there, although it was not blooming in Unity (Also I never added a post-processing feature of blooming). Again I tried to test the build in Xcode, but it wasn’t blooming there either. It seems to be a distribution issue. Thanks for any help in advance.
STEPS TO REPRODUCE PROBLEM: When going onto a certain build on the App Store/TestFlight, around half of the devices bloom the scenes and the other half are fine. None of this blooming occurs in Xcode or Unity, only in TestFlight and the App Store.
