Rebecca is wonderful. She suggested taking my vehicle in. I was also contacted by Ford Motor Company, on a separate tech issue with the site, and they advised me that the update was not showing in my particular situation because of two recent recalls that needed to be addressed. I took my car in, got the recalls taken care of, and my SYNC is now updated to 3.8. I'm crossing my fingers this makes it work much better. My only concern now is that 911 Assist is no longer an option in the 3.8 interface.
