Missing restore mechanism
We found that your app offers In-App Purchase(s) that can be restored but does not include a “Restore Purchases” feature to allow users to restore the previously purchased In-App Purchase(s), as specified in the “Restoring Purchase Products” section of the In-App Purchase Programming Guide
“Users restore transactions to maintain access to content they’ve already purchased. For example, when they upgrade to a new phone, they don’t lose all of the items they purchased on the old phone. Include some mechanism in your app to let the user restore their purchases, such as a Restore Purchases button.”
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.
– Your app was not optimized to support the device screen size or resolution.
Specifically, your app is displayed the black bars on the sides of the screen when run on the iPad.
