Ok, so I got both Track and Follow working with the help of Litchi email support.
The reason that Track was not working as it should is due to a software bug that causes the zoom to automatically go to 2X when Track is initiated if you’re recording in anything less than 4K. This is not supposed to happen, Litchi is aware of this and it will be fixed in a future release. A temporary work around is to hold the fn button and use the left finger wheel to zoom back to 1X. Then it worked great for me.
The Follow mode still wouldn’t work even though I had read the manual and watched every tutorial I could find. Location services was on and shared but still wouldn’t work. I noticed that when I hit the button “Set to aircraft position” the height would update to current but the distance would stay at default, this was an indication that my phone wasn’t actually sharing location with Litchi even though it was set to. What finally worked for me was to disable location services on my phone, reboot the phone then re-enable location services.
Hope this helps someone else!
