We had several users whose subscription suddenly disappeared from the last week. They all got a system dialog showing the purchase was from another Apple ID when restoring purchase, and they were logged-in with exactly the same ID they used to purchase.
Is there anything wrong with StoreKit?
SKReceiptRefreshRequest also failed with below error:
