IOS app rejected due to unity IAP IPV6 Issue.

Its literally my first game!
notes:
- IAP functioning 100% on android!
- button dims when pressed so clearly it shows if its clicked or not.
- once button is pressed it also clearly shows its already owned non-consumable.
- when I turn my mac to IPV6 router.. then connect my iphone to it .. then I test the button again nothing happens!

code:

 using System.Collections.Generic;

 using UnityEngine.Purchasing;
