Bug Check: CloudKit MacCatalyst didReceiveRemoteNotification

问题

I am using MacCatalyst to port an iOS/iPadOS app to MacOS. The app uses CloudKit and functions in all ways except one: the UIApplicationDelegate method, didReceiveRemoteNotification, is not called on the MacOS version when a CloudKit update is submitted from another device

Things that do work in the app:

• Submitting CKDatabaseOperations including updates and subscriptions to CloudKit
• Manually retrieving database updates from CloudKit
• UIApplicationDelegate method didRegisterForRemoteNotificationsWithDeviceToken fires and UIApplication.isRegisteredForRemoteNotifications returns true when calling UIApplication.registerForRemoteNotifications
• Setting the CKSubscription.NotificationInfo to invoke an alert notification which displays properly in MacOS
• UNUserNotificationCenterDelegate method, willPresent, when an alert notification is invoked and the app is in the foreground
• didReceiveRemoteNotification on iOS and iPad (physical devices)

Has anyone had UIApplicationDelegate method, didReceiveRemoteNotification, called when using MacCatalyst?

Update: The app did eventually fire the didReceiveRemoteNotification method 30 minutes after an update was sent, but on other updates, the method is not fired even after hours. Any ideas?
