Drone missions can be quite unpredictable sometimes. Did you miss the opportunity to perform a particular drone mission at your location, then you can simply cancel the mission. This can be done by going to the details of your approved order and click edit. Scroll down and select a particular mission you want to cancel. Change the status to “cancelled” and update order. You’ll see that the price of this mission changed to 0 and it will no longer be possible to upload this particular mission.
