If an app on the App Store still uses StoreKit 1 (a.k.a. the Original StoreKit) to handle In-App Purchases, would IAPs work for users who download such app on iOS 26.2?
Would the app allow the users to purchase an IAP via StoreKit 1 or would it be impossible to buy the IAP on iOS 26?
The iOS Documentation says that SKPaymentQueue (which is a part of StoreKit 1) is "Deprecated" and "No longer supported.", with the support being for iOS 3.0–18.0.
Does this mean that apps using StoreKit 1 won't be able to make IAP purchases when running on iOS 26?
