I find that once you actually get the waypoint mission recorded, it executes that mission just fine but for some reason I did remember getting errors when I was recording the waypoints. I seem to remember these were something like 'invalid waypoint'. I just kept re-creating the waypoint mission until it worked - never figured out why.
Agree, Lichi's waypoint mission is easier that DJI Go's because you can plan it on a map, with DJI Go, you actually have to visit each location, which could, I guess be a safety feature because you will have actually flown the route manually. But the worst is that the DJI Go Waypoint automatic flight mode doesn't store or execute gimbal positions, whereas Lichi does. You could, for example, plot a route around a point of interest from a low altitude to high but your gimbal pitch won't change so you end up losing the shot. It's OK, but it needs work.
