If you have Mini 3 Pro and the active track doesn´t appear on the display, you´re using the drone probably as a beginner. In DJI Fly, go into the Menu, then Control and quite down the Flight Tutorial. Your aircraft must be connected. Then go through the whole tutorial which consitsts of proving of all the basic functions of the aircraft. When the tutorial is over, your active track modus will be activated. You can start your drone and once more in the menu -> Control, there is a function: Allow to scan objects (or something like that :-)). Turn on this function and test your active track.....   I hope it will be helpfull, it took me a lot of time to find and activate this function....
