App Rejected on App Store due to IPv6

I have used unity version 5.3.4f1

I’ve integrated soomla InApp purchase, Google AdMob and Native Share

Game is rejected on AppStore with the following reason:
“Performance - 2.1
We discovered one or more bugs in your app when reviewed on iPad running iOS 9.3.5 on Wi-Fi connected to an IPv6 network.
Specifically, the app doesn’t remove ads even after purchasing the In-App Purchase element for ad removal. ”

They don’t complain about IPv6, that’s just a statement from Apple how their testing environment looks like.

The reason why it’s rejected is that you do not disable \ remove your ads once the user purchased the “remove ads” inapp purchase. So your app appears to commit fraud. You must remove your ads when the user pays for adremoval reliably.
