Ford Sync DOESN'T Sync anymore, and it's bugging me!

My original iPhone 6 was rock-solid with SYNC, including reading text messages even though Ford says that it's incompatible. Then it was replaced and cloned from the 1st phone and there are a handful of issues showing up now. No more text message reading, and it will occasionally just drop the BT for no reason for 15-30sec, then reconnect. I have had the opposite problem with both devices generating a pass key for the other, and neither has a place to enter one... Have you looked at the Ford forums on this?
