I planned a mission on my laptop and didnt see the large red circle on the map but when I went to launch I kept getting "mission error" I looked at the mission on my tablet and saw the red circle and noticed my furthest waypoint was outside of it. I adjusted this waypoint to inside the red circle and it flew without issue. Even at the furthest waypoint, I had plenty of signal strength. What is this circle for and can it b adjusted? Thanks!
