The app scheduled this snapshot.
Declaration
case appScheduledDiscussion
You can schedule snapshots either by calling the scheduleSnapshotRefresh(withPreferredDate:userInfo:scheduledCompletion:) method, or—when completing a background task—by calling the setTaskCompletedWithSnapshot(_:) method and passing true.
These snapshot refresh tasks are only triggered when the watchOS app is in the dock.
