I attempted to fly a map I had loaded on Drone Deploy...Using a Phantom 4A the op started and the drone went about 100 yards and stopped and would only hoover...brought it back and restarted every thing...same result 3 times...contacted support and ran a firmware update at their suggestion...same result...Just for kicks I tried the op with a Zoom I had with...started fine and stopped at the same spot...on the zoom controller I noticed a mag interference warning...any thoughts or suggestions?
