I've had this gimbal for less than a year and to my knowledge there has NEVER been any type of update.  ActiveTrack just stopped working a few days ago.  Yes it shows up on the screen to select, however, when I go to select the object/person, it will not pick up on it and therefore it is not working.  I tried to see if I needed to do a software update and I kept getting an error mesage (screenshot of error message attached).  Yes I am connected to wifi, so that is not the issue.  
I got this gimbal with a pre-order promotion with Sprint less than a year ago.  I have the LG V40 ThinQ.  ActiveTrack and all other fuctions worked up until recent.

"Thanks for waiting. I checked with our engineers and was advised that they are currently refactoring the code of ActiveTrack for the Osmo Mobile and Osmo Mobile 2, so this function is temporarily unavailable with DJI GO for Android V3.1.58.
This issue is expected to be fixed by the next version of the app."
They told me literally that on technical support, so we just have to wait fornthe next version!
