I followed https://developer.apple.com/documentation/storekit/in-app_purchase/testing_in-app_purchases_with_sandbox?language=objc to test. Begin testing, from step 1 to step 9, all works well.

No matter clicking cancel or ok, it has the same action - close popup. BTW, I also tested with Xcode StoreKit. The problem is: our app cannot directly run debug, we usually run the app on device and choose 'attach process'. The StoreKit transaction managers seems doesn't support 'attach process', right?
