Thank you for the information - so why was this different before the 16.0.2 update? When I first set up the iPhone the camera switching was there

If only you ever responded to feedback. I have told you about a lot of issues in StoreKit on watchOS - 3 months ago (on September 18 this year) - and haven't received a single comment back from you. So many users are having issues with purchases on watchOS and put the blame on us developers. I'd love to assist with solving these problems with you but you don't even respond back. I don't understand this to be honest.
