Our app has implemented the handoff functionality between push notification on the Apple Watch (in our WKUserNotificationInterfaceController subclass) and the main iPhone app. It works with dynamic interface of the notification long look.

I also noticed that handoff does work from static long looks of:
Anyone noticed this problem too? Are there any workarounds that make handoff work from a static long look?
