This sounds like it should be working, but a couple of things to narrow it down.Having watched all the videos I noted the temperature was 48F- the battery was cold, the destination was an EA DC fast charging station, chosen from the native nav system. The distance to it was under 30 miles, and 30 minutes, there was 38% state of charge. by every videos "requirements" it should have worked.
Double check that the option is selected, sometimes it turns itself off.
Try another DCFC. I’m assuming you’re selected from the POI categories, not manually entering the location.
If that fails, pick up a OB2 dongle (that works with your phone :/ ) and double check your minimum and maximum cell temps, as well as the battery heater temperature. If the cell temp is close to 70° it may not activate
