How do you record a mission? I have taken off. Turned on "Record"(icon yellow), proceeded to waypoint 1, zoomed in on the subject, pressed the "photo" button to capture that waypoint and photo, and repeated a few times. Once I finish, I turned "Record" (icon white) off. I then land. When I go back and check saved missions, I do not see any new missions saved. What am I doing wrong?
