In my app, when invoking a Shortcut via Siri, the application(_:continueUserActivity:restorationHandler:) method in AppDelegate is called twice. When I debug, both NSUserActivity objects are identical. However, when I run the same Shortcut by tapping it manually, the method is only called once as expected. Has anyone experienced this issue? How can I prevent Siri Shortcuts from delivering the same NSUserActivity twice?
