So, when I got home from our trip, I found the unpublished Ford/Lincoln Mobile Application support phone line @ 877-945-3648. I called them. They forwarded my concern to Engineering. After a few days, the authorization screen appeared on my MKC. I approved it. My Lincoln Mobile Ap is now working. Apparently, they found their reset program. Yeah.

I went through the exact same process as you - with no acknowledgement from Lincoln! After my 3rd or 4th call to support, it mysteriously started working. I have used it extensively through the winter and will probably do the same with the A/C in the hot months.
