When my developer and I properly formatted all of the iPhones and iPads on Xcode, we then released the app to TestFlight for beta testing. We noticed an unexpected error, some devices would display the app properly but some other devices would display a very jumbled and disarray app. For example, we began testing the app on three separate iPhone SEs. One of the SEs appeared perfect, just as designed on XCode, but the other two would appear broken and unusable. In layman’s terms, I would say that it appears as if an iPhone X build is showing up on an iPhone SE, so cosmetically it appears messed up, but also it has many functionality problems. We also saw this problem with an iPhone 8. I am not sure if this is a TestFlight glitch. Is this a common issue with a known fix?
