Updated mavic to latest firmware. Now problems using Litchi, be careful. Setup 29 waypoint mission, speeds were all set to cruising, but speed was all over the place sometimes slowing to 3 mph (cruise was set to 24 mph). Also Last waypoint set to pause 10 seconds then reverse waypoints but Mavic just stayed there hovering. Did not reverse mission as set in Litchi. Fortunately had radio link and was able to go to Sport Mode, cancelling mission and flew back at steady 35 mph no problem.
