Hello,
We have 2 renewable subscription products the player can choose to subscribe to in order to get access to our game's main content.
We've been going back and forth with Apple for a few weeks now, and for some reason, the purchase flow looks to fail for them. After a few submission builds, I'm being led to believe that they're getting a fail during the receipt validation step.
When players either choose "Join" or "Launch Game" (for players that are already members), we do the same exact logic path:
First validate that they already have a valid subscription:
1) Refresh player receipt and get it in base64 format (we use Prime31 store kit for this).
2) For each known known subscription product, get its centesimal value along with our base 64 receipt and call iOSValidateReceipt. We only expect fail callbacks to this (which might sound a little strange). The expected error codes for new players being ReceiptDoesNotContainInAppItems (altho any other error code would behave the same way, with the exception being SubscriptionAlreadyTaken) and returning players being SubscriptionAlreadyTaken. If we get the SubscriptionAlreadyTaken error code, we terminate this routine early.
If player has a valid subscription:
1) Just put them in the game, simple enough.
If player doesn't have valid subscription:
1) We put them through a parental gate, and only continue if they correctly answer all questions.
2) After parental gate, we show a native apple popup prompting them to choose which subscription product they wish to purchase.
3) We take their selection (which maps to a product id), and purchase it through Prime31's StoreKit. If the purchase is successful, we refresh the player's receipt, and send that receipt to Playfab via a call to iOSValidateReceipt with the proper centesimal value. If this is successful, we deem them subscribed and put them in the game.
Now that I've laid out the entire logic path for our purchase flow, is there a reason why this would only fail for the app review team? Our team has tested this numerous amounts of times with existing/new sandbox user accounts.
I would assume that the server implementation for iOSValidateReceipt would always hit apple's production endpoint, then fallback to their sandbox endpoint when doing the receipt validation. Is this correct?
I would greatly appreciate any helpful nudge to this. Thank you so much!
