I am mystified as to what makes DJI Go save a waypoints mission as a favorite. I've tried several times to create a waypoint mission. Sometimes it gets saved as a favorite, and (usually) not. When I record a series of waypoints an hit done, there is an apply button that would let me run the mission right away. It seems that if I don't apply the mission I just recorded, it gets discarded?!? I have recorded the same complex mission twice, and both times it got discarded. This is really stupid. The waypoints feature is very cool, but the implementation in DJI Go leaves a lot to be desired. When I click done, I expect an option to either save or discard the mission. I also cannot believe that there is no option to name a mission.
