Same here, started I believe with Xcode 16.3 and our app does not implement or have any notification methods.

There has been some public forum postings on IAP not working for the last month (Dec '24) or so with iOS 18.2+ https://discussions.apple.com/thread/255902528?sortBy=rank&page=1 I can confirm on multiple iOS iPhone devices, IAP does not work in our app on iOS 18.1.1+, it throws the following error: Received error that does not have a corresponding StoreKit Error: Error Domain=AMSErrorDomain Code=10 "Payment Sheet Failed Presentation failed" The above IAP sheet appears correctly iOS iPhone device on 16.4+, 17+, and up to 18.1, but not 18.1.1 Xcode iPhone simulators are IAP working from 16.4+ up to 18.2 From the above forum link, it appears Apple has promised a fix at 18.3 I guess it's a wait and see.
