I am having the similar problem.
Restore purchase with sandbox account fails in TestFlight beta app on iOS 15.1.1
On ios14.8 it's fine.
On ios15.1.1, when I use a sandbox account for in-app purchase on a beta app installed from TestFlight, the purchase succeeds, but restore fails.
When I try to restore it, every time I get a dialog to enter apple id and password, I enter the sandbox account I purchased, but it fails with 'unknown error'.
I checked the device logs and found the same situation as written by gmarcus.
Is this a specification of IOS15 or a bug?
Have you found a solution to this problem?
Any information or suggestions?
Thank you.

It was the same with beta8.
It was the same with iOS16RC.
Note that I found that the problem with windowScene.interfaceOrientation in this case is that the update timing is too late. It seems that it is not updated to the correct value until about 20-50 ms after viewDidAppear.
viewWillTransitionToSize is not called no matter how long I wait.
Is Apple not willing to fix this issue?
It was the same on iOS16RC&xcode14RC. Posted: FB 11480364
