Transaction.unfinished not getting unfinished transactions

I am testing auto renewing subscriptions for a macOS program in Xcode with a local Storekit file.

I have renewals set to occur every minute for testing.

I quit the app, and watch renewals appear in the Debug transaction manager window. Each is marked unfinished.

When I start the app, I call a function that is supposed to get unfinished transactions and finish them. In one of those "I swore it worked the other day", I am now finding it isn't working. The unfinished transaction remain marked as unfinished.

func getUnfinished() async {
    for await verificationResult in Transaction.unfinished {
        guard case .verified(let transaction) = verificationResult else {
            continue
        }
        
        await transaction.finish()
    }
}

If I add an AppStore.sync() right before looping on Transaction.unfinished, it works (i.e., cleans up unfinished transactions), but I get an alert I have to click through.

do {
        try await AppStore.sync()
    } catch {
        print("DEBUG UNFINISHED: AppStore.sync() failed: \(error)")
    }

Any idea why Transaction.unfinished isn't fetching unfinished transactions for me (without the AppStore.sync)?
