Hello,This is my first post in Apple dev forums.If you have integrated with appstore for renewable subscriptions, you probably know by now how bad the overall experience is. A couple of weeks ago I noticed that Apple updated their server-to-server notifications docs.They are going to deprecate certain notification types and introduced new/changed objects. One object in particular is `unified_receipt` https://developer.apple.com/documentation/appstoreservernotifications/unified_receiptBedides many other inconsistencies in the docs and what their API actually returns, I want to focus on unified_receipt. In Sandbox, Appstore still returns an old payload (no unified_receipt), but I noticed that in Production unified_receipt is there. How does that make any sense? Why cannot Apple get such an important, yet very simple thing get right?
