After the release of StoreKit 2.0, the in-app purchase failure rate increased by 63.19%, with the majority of errors being StoreKitError.unknown. When encountering this error, many users repeatedly attempt to make a purchase, but the outcome remains unchanged, resulting in the same unknown error. In some cases, users who wait approximately 2 minutes before retrying the purchase may either succeed or encounter the following error: “StoreKit.StoreKitError.systemError(Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.storekitd”)”. This issue has directly impacted our app's purchasing flow. Because our app only displays the promotional purchase offer once, these issues have significantly reduced the number of users successfully completing the offer. As a result, the conversion rate for this promotion has dropped well below expectations, negatively impacting our business metrics.
