问题
Whenever I query for past CKNotifications using CKFetchNotificationChangesOperation, I keep on getting a whole bunch that are marked as CKNotificationTypeReadNotification. And indeed, I have read them before, marked them as read (using CKMarkNotificationsReadOperation), and am updating my lastServerChangeToken when querying.
Why do they keep showing up?
Thanks.

This started working…and, unfortunately, I'm not sure why.
