We are using apple's verifyReceipt API. (https://buy.itunes.apple.com/verifyReceipt)
In one receipt, it returns a status of 21005. This probrem is occured by not all receipt but one receipt.
The documentation describes it as "The receipt server was temporarily unable to provide the receipt. Try again.". (https://developer.apple.com/documentation/appstorereceipts/status)
However, after more than a month, the API still returns the same status for this receipt. Does anyone know the cause of this?
