"Show In-App Purchases" Not Showing In App Store
Solution 1:
I was having same problem for my new app - submitted a question to apple support - they replied:
The In-App Purchases section of your app’s product page will contain the top In-App Purchases for the app only after a minimum purchase requisite has been reached. If the number of completed In-App Purchases doesn’t exceed the minimum threshold, this area will not appear.
Solution 2:
It is now showing my In-App Purchases on the App Store.
It just takes a couple days or so to appear on the App Store.
