Update: Never got an email that it was shipped but my adapter was delivered, by FedEx, yesterday with a shipping date of Dec. 5th. It came from Dearborn.
I had a similar experience, last week, from Beach Ford Mobile Service in Myrtle Beach, SC. They came to my house in North Myrtle Beach and did the same updates. He didn't connect to the 12 volt battery, he plugged my car into my Juicebox which unknowingly caused the update to fail several times...

Went back out around 11:00, turned it on to run a/c, got a 12volt battery fault, service soon message, I guess that's maybe why it's failing. I haven't driven it much in the last two weeks. Maybe I need to go for a long ride today.
Got in my car yesterday to see if I'd gotten this update and noticed that Auto Updates was turned off for some reason. Toggled it on and got the update available screen that everyone's posting in this thread. Tapped the Update Now button, got out of the car and locked it up. A few minutes later...
