We have a native iOS app that supports the upload and display of USDZ files. It has been working great since beta (late 2022) and live launch (late 2023) until now. But recently we had reports from some users on Max model phones (14 + 15 Pro Max) at least. When they launch tap and launch a 3D file the Quick Look player is triggered. So far so good. But for affected users the controls along the top of the player - X (close) AR | Object (toggle) and share button - are moving too high up the phone screen and getting stuck (untappable) behind the phone's top status bar (time, camera bug, connection, battery). This means that when they open a USDZ file in AR or 3D view they have to hard-close the app to get out of it again. This doesn't happen when they open a USDZ file from Files, Dropbox etc on their phone (which also uses the Quick Look player). The controls only move up and get stuck when launching a USDZ from within our app. I'm at a loss to figure out what might be causing this on some phones and not all others. And why only when opening a USDZ file from our app! So far we have replicated this issue on a single iphone 14 Pro Max and a 15Pro Max, both running iOS18+ We have tested on other 15Pro Max's on same OS, and Pros, normal iPhones, Minis and are not experiencing the issue. You would think that a USDZ file is a USDZ file and that your iPhone knows what to do with it and open it in the Quick Look player regardless of where you open the file from. Why would the navigation items be moving if you open the USDZ file from within our app, and why only for some select users? We will continue to troubleshoot and test but I wanted to throw this out to the community in case anyone had experienced this or if anyone had any theories that would expedite our testing. Your thoughts are most appeciated! Here is a video showing the expected (correct) behaviour: https://www.dropbox.com/scl/fi/0sp8s4opaf2m4gukkcbrk/How-opening-a-USDZ-should-behave_correct-behaviour.MP4?rlkey=tzzau9x91mwox66gsgguryhep&st=qiykmne9&dl=0 and a screenSHOT attached below of what is happening on one of the affected user's iPhone 15Pro Max.
