2000m restriction warning message

Q: I can not upload a route because the distance of the first and last waypoint is more than 2000m. How can overecome this problem?

DJI restriction is 2000m between two adjacent waypoints, first and last, waypoints are considered as adjacent too for some DJI drones. For the Mavic series, the first and last point may be further than 2 kilometers.
If it is necessary to finish the mission within more than 2000m from the takeoff position, you have to create a route to your desired location, then add additional waypoints back to the takeoff location, so the last waypoint is closer than 2000m. At the real landing location, you can add wait action, so the drone stays in the air. When the drone has reached the location, overtake control and land the drone manually.
