I can install my app from AppStore and Xcode without any problems on all 4 of my devices which range from iPhone 12-8. However, when some customers update to the newest version, it hangs at the launch screen. I have asked them to delete and reinstall it, and they were not successful. I can not duplicate it on my devices, but I ask a few friends, and it hung. But, I do not have access to their device. I don't know where to start.
