Flew a waypoint misson with my Spark yesterday. Worked out pretty nice except for the 360° panorama action I've set on a waypoint. Status continuously switched between "preparing picture 1" and "idle". Had to stop the mission and flyback manually. Then tried a 360° Panorama on itself, not within a waypoint mission. Some behavior. Stuck on "preparing picture 1" and "idle". A 180° panorama worked fine. Seems the Spark cannot do a 360° panorama. If so, Autopilot should give a warning when you try instead of getting stuck.
