Previously, opening and closing the contacts app on my iPhone 6 initiated a sync for contacts linked to my Microsoft Exchange account. Tapping on "Groups" from within Contacts and then tapping and dragging down on the screen while in "Groups" was also another way to initiate an immediate sync even with the sync frequency set to "Push". Now, in iOS 9.2, none of the methods work for forcing a contacts sync. This does not work even with sync frequency set to either "Push" or "Manual". The above steps work for Calendar but not for contacts. Is there another way to force an immediate sync for Contacts linked to Exchange?
