Hi, I’m investigating switching from the /verifyReceipt
endpoint to the App Store Server API.
I’ve noticed that some transaction IDs we have in our system return 4040001 (AccountNotFound) from the “Get All Subscription Statuses” endpoint.
These transaction IDs are associated with receipts that used to verify OK with the /verifyReceipt
endpoint, but now return 21010 (receipt unauthorized).
Under what circumstances do transactions which used to be valid start returning “account not found”?

21010 The system can’t find the user account or the user account has been deleted.
