I stayed up late last night on Litchi's Mission Hub setting up an epic mission to fly this morning. When I got out to launch, I put the bird up close to the first waypoint and its altitude and hit play. It came up with an error message saying I was to high. Tried a few times,,, nothing. Came down to about 10' and tried,,, too high. Landed, took off again and hovered at about 2 ft, tried again, too high. Finally gave up. This is the second time this has happened to me.
