We are experiencing an issue with StoreKit in the sandbox environment. When performing an SKProductsRequest, some or all of the product identifiers we provide are returning in invalidProductIdentifiers of SKProductsResponse, even though all of them are valid and approved.
This issue started occurring today and seems intermittent—occasionally, a previously failing product identifier works after one or two retries without any changes on our end.
We have verified that:
All product identifiers are correctly configured and approved in App Store Connect.
There are no recent changes to our product configuration.
The same identifiers have worked previously without issue.
Could you please assist us in identifying the cause of this behavior or let us know if there is an ongoing issue affecting StoreKit sandbox services?
Thank you for your support.
