I took my drone into Innovative UAS for general maintenance, new control arm modules, Quick release folding Propeller Base and Spring, Lens Glass, nothing that should effect any sensors. My test flight yesterday, I get a Downward Altitude Sensor Data error, had 3 drones in the past, never seen this error before. Drone began to drop and land on its own, without typical pause it will do before landing. Is there anything I can do to resolve this issue myself, or does it need to go back to the repair place. Was already out 3 weeks, typical turn around time these days 3-5 weeks thru DJI repair facility. Hoping someone has had this issue maybe resolved it, appreciate any feedback, thx
