AppStore promotion page shows: doesn’t include the SKPaymentTransactionObserver method.

The following information is displayed on the promotion management page of the AppStore:

`These in-app purchases can’t be promoted on the App Store because your latest approved binary doesn’t include the SKPaymentTransactionObserver method.`

We want users to purchase our products directly in the AppStore, but due to this prompt, we seem to be unable to participate in this promotion plan.

Because we understand that we have executed the `SwiftyStoreKit.completeTransactions` method in `didFinishLaunching`, and our delegated permissions have been submitted. How should we complete this test now? We don't know how to solve this problem.
