I have a subscription app which is currently on the app store. In preparation for iOS 11's new App Store look / feel we wanted to test the ability to IAP straight from the App Store. Through iTC under Features / In-app Purchases, I submitted a 1-month and 1-year IAP along with localized copy and the App Store Promotional Image. After a few days both In-App Purchases came back as "Promotional Metadata" rejected. Normally you would check out the App Review tab but no such tab was presented.
I started this simply to test out how our IAP's would look in the iOS 11 beta App Store and ideally to test their functionality. I would assume if developers are unable to test this on the beta then these submission fields should be hidden until Apple is ready.
How do we the developers test that our App Store IAP's work with our app before making it live to the public? If we are unable to test during the beta will be given a week or so to test on the office iOS 11 market place?
Would love any information retaining these questions.
