I am not sure if this is the right place to ask, but it can be. I created a .Net MAUI app (iOS) and built it with Azure DevOps. Our tester downloaded it from AppCenter and installed on his iPhone. He was not able to open it with the following error:
"My App" Needs To Be Updated. The developer of this app needs to update it to work with this version of iOS."
But I used the app on two different iPhones (also after downloading it from AppCenter), one of which had the same iOS version as the tester's phone (15.7), and they both work without problem.
The tester's device is registered with the testing provisioning profile, as well as the other two devices that have no problems.
What can be causing the issue? And how is it supposed to be updated?
