App's resolution scaled up on iOS

Hi there! I am facing an issue on iOS. The app resolution is totally out of scale, it is like 4 times bigger than it should. The main issue is that this was detected only by Apple’s reviewers while they were reviewing the app’s submission (on an 11-inch iPad Pro), thus I have no access to debug tools. I have tried to reproduce it in different devices and simulators but had not the same result. Anyone here ever faced something like that, have some clue or tip to help?

The issue is like This but in the opposite way (the app is bigger than it should)
