Hello house, i had a minor crash with my mavic pro and i cracked my gimbal and flex so to tilt my camera wit my R.C is a major problem.....anyways i got that fix but now, my obstacle avoidance particularly downward sensors aren't functional any longer, having tried calibrating with the square_like movement prompted after i pushed the calibration option provided but even after that, it still fails and shows system error on my RC and also shows downward obstacle failed (something of that nature) my question is will dji assist help the mater or i should just conclude the obstacle avoidance is broken?
