We have a server to server setup for subscription management for the Apple subscriptions. Lately we observed that we are getting a lot of DID_RENEW notification, after decoded with the /verifyReceipt endpoints, these notifications have no purchase in them. We are in the Production environment. The original_purchase_date is set to "1970-01-20 11:45:27 Etc/GMT" and we can se also the preorder_date field set to the date when we receive the notification. All our products are approved and released at the moment(nothing to be released). There are no other "usable" details for us in the decoded notification(data to identify user).
Can somebody please help explaining this scenario? Why are we receiving these notifications?
Thanks, David.
