Having a problem with getting my camera to tilt up and down. I have the Phantom 4 Pro + V2 and this started after a firmware update. The camera itself works but will not tilt up or down. After takeoff flight becomes very shaky as if I'm flying in turbulent wind. I have done all firmware updates and calibrated also. Did a reset on the controller and none of this has solved the problem. Any suggestions on what the issue might be?
