I recently submitted my app to Apple for approval and it was rejected, this time because the binary allows a feature to restore "previously purchased In-App Purchase products"; however, in iTunes Connect I have something setup in the In-App Purchases, and the price of the app is set to free.
Here is the message from apple:
Restoring In-App Purchase
We found that your app includes a feature to restore previously purchased In-App Purchase products.
It would be appropriate to revise your binary to remove this feature.
