All these posts motivated me to contact the Sync group with Ford again. Finally, the web chat person gave me a phone number to call 833-389-0848. That lady was pretty helpful - she confirmed at least that my dealer did reach out to TAC on the issue when my vehicle was there. She did say that 4 days later, they advised my dealer that the GWM software needed to be updated and then the APIM software. I believe my vehicle was no longer there (as they said there was nothing more they could do), but bummer that the dealer didn't see that advice and reach out to me.
Ford agrees that there is something wrong with my truck as they see no updates happening since I took delivery 13 months ago. So, my choice is to go to another dealer or continue to push my selling dealer.
For now, I'm choosing the latter and am dropping off my truck again on Friday. My service advisor is out until Thursday morning, I will talk to him directly to make sure we are on the same page.
I hope the third time is the charm. If not, I guess I'll need to take it to another dealer.
