I read the thread "lost at sea" and I had the same problem. While fishing 80 miles offshore, at a slow troll i launched my Mavic Pro from hand it went up and down but would not move forward or backward. I have not installed the latest update and it has worked in the past thank God It was almost out of sight but i was able to maneuver my boat under it and lower the drone.....I thought it was a goner fore sure! I'm a newby only been flying a few months what the heck happened and how do i fix the problem? I'm 57 so go easy lol
