I submitted for the first time an update of an app with in app purchase option. If you press the button to purchase and you already purchased it you're not charged, but...
We found that while your app offers In-App Purchase(s) that can be restored, it does not include the required "Restore" feature to allow users to restore the previously purchased In-App Purchase(s), as specified in Restoring Transactions section of the In-App Purchase Programming Guide:
"...if your application supports product types that must be restorable, you must include an interface that allows users to restore these purchases. This interface allows a user to add the product to other devices or, if the original device was wiped, to restore the transaction on the original device."
To restore previously purchased In-App Purchase products, it would be appropriate to provide a "Restore" button and initiate the restore process when the "Restore" button is tapped by the user.
For more information about restoring transactions and verifying store receipt, please refer to the In-App Purchase Programming Guide.
what should I do? another button pointing to the same function but named 'restore'.....? or maybe it's a feature not included on NK?
