Hi, I have a paid app in the Mac App Store, and I want to verify that the user purchased the app legitimately. Does the StoreKit2 framework have an easy way to determine this? From the documentation I've seen, I believe the 'Transaction.currentEntitlements' call will only return transactions for IAP and subscriptions. I would assume that 'Transaction.all' would work, but when I run the app (with Xcode debugger attached) I get no results.

What's the best way to test this out for an app that's going to be paid-up-front?

This is what the documentation says about Transaction.all: This sequence returns the user’s transaction history current to the moment you access the sequence. The sequence emits a finite number of transactions. If the App Store processes new transactions for the user while you’re accessing this sequence, the new transactions appear in the transaction listener, updates. The transaction history doesn’t include finished consumable products or finished non-renewing subscriptions, repurchased non-consumable products or subscriptions, or restored purchases.

Even after reading this, I'm not 100% sure if paid apps transactions should show up in the transaction history or not.
