I am sorry, I did not mean to post an answer. I clicked Add a Comment, was asked to sign in and then presented with a text field. That text field posted an answer instead of a comment. And I cannot delete the answer.

You have confirmed the difference. I have seen the difference. There is a bug in iOS 15. Will it really help if I post more code? I have not yet filed a bug report for this. I have filed a bug report for another iOS 15 bug that is more severe: FB9669244. I was baffled that there was nothing on the internet about this slider bug so I wanted to post here first. The feedback assistant is a little black holeish. Thank you very much for taking the time to confirm this iOS 15 bug.

Bug reported FB9717666.

Thanks for your generous answer. I am however not using the receipt. The SKPaymentTransactionObserver could provide the info we need, but it seems it is not.

Here's how one would expect SKPaymentTransactionObserver to work: 1.0) Observe restore only for items that are not expired or refunded (like the StoreKit config file does). 2.0) There is already a date sent to the observer. Why not make it a useful date, like subscription expiry date? 2.1) Observe purchase only once per payment or renewal (not important if we get the useful date).

No, I changed from turning it off when the user is inactive to only turning it off when the app goes to background. That way there are a lot fewer clicks. But it is still clicking. Could not find out why it was clicking. Had to give up. It's on the App store now.

Thanks. I got an answer to my bug report where they told me the right way to do this. I do not remember exactly what the command was that they told me to use, but I think I remember it solving the problem. I am no longer ashamed of the orientation changes, so it must have worked. I think the command had "subview" in it, maybe layoutSubview or something.

This is the answer I got in the feedback assistant: Engineering has provided the following information regarding this issue: updateUIView is not necessarily called on bounds change. You should override layoutSubviews in your hosted view. I have moved away from iOS and am C++ in Visual studio now, different computer, so I do not have the solution easily available.
