I'm trying to add the App Store Promotion where you can submit a 1024*1024px image to a inapp purchase. And then it will display on app store and such. This requires:
These in-app purchases can’t be promoted on the App Store because your latest approved binary doesn’t include the SKPaymentTransactionObserver method.
And then it links me to this: https://developer.apple.com/documentation/storekit/skpaymenttransactionobserver/2877502-paymentqueue
I already have the CrossInAppBilling stuff done. But this is something else and I cant seem to find any examples for it. It wants me to use the StoreKit reference from my .iOS project but thats about as much as I understand. Any suggestions, url or anything would be appreciated.
