I was having connectivity this past week. This is what resolved my problem.
1. Make sure Setttings->Network->Vehicle Connectivity in ON
2. Go into Settings->Privacy->Data sharing with Lincoln and turn everything on. You probably only need Share Vehicle Data On but to be safe turn all on for now.
3. Reboot your phone so Lincoln App resets
Hope that helps. Things aren’t as bad as they seem, but there are not a lot of resources out there for help.
i have a new problem discovered today where my car no longer sees any networks when parked in my garage. But just now, I checked it and it’s connected to my network again
