I use In-App Purchasing.
We discovered one or more bugs in your app when reviewed on an iPad running iOS 11.2 on Wi-Fi connected to an IPv6 network.
During review, we were unable to complete the offered In-App Purchase.
I am using the StoreKit created By Jason K. Im not sure what to do now as i dont have control over this anywhere i can see.
Xojo release 3 came out the day after and supports Ipad 5th Gen with IOS 11.1 so i tested and sure enough it fails. It physically works on my Iphone 8 with 11.1 and my Ipad with 9.35.
How have others got theirs past this... What should I try?
