I enjoy doing brief (2-4 waypoints) GS missions just for the pleasure of it and lately, I've noticed something a little strange. During the mission, I notice from the phone's screen that it pops up a message saying, "send XX waypoints...." This often happens after the first waypoint has been reached and it's heading for the next one. Once, I'm pretty sure the quad turned the wrong way at a waypoint, paused, turn the correct direction and continued the mission. So far, all missions have been completed with no problems, but I'm puzzled by the waypoints being re-sent in mid-mission. Has anybody else noticed this and should I be worried?
