We’re encountering a problem with StoreKit in the sandbox environment. During an SKProductsRequest, some or all of the product identifiers provided are being returned in the invalidProductIdentifiers array of the SKProductsResponse, despite being valid and already approved.
This behavior began occurring since last 2 days only and appears to be intermittent—in some cases, a product identifier that initially fails will succeed after one or two retries, without any changes on our end.
What we've verified:
All product identifiers are correctly configured and approved in App Store Connect.
No recent changes have been made to our product configuration.
The same product identifiers have previously worked without issue.
We would appreciate any assistance in identifying the root cause of this behavior. Please also let us know if there is a known issue currently affecting StoreKit sandbox services.
Thank you for your support.
