On our most recent version of our game on IOS we have noticed that a few people have failed to validate their receipts with the error ReceiptDoesNotContainInAppItems. From what I have found the receipt data that playfab returns has "in_app": [] causing this error. Players are still getting charged from apple but not receiving items. Title ID: 33F0 one of the effected userID: 72D07E98754233D9
