Software is all up to date. The gimbal seems to 'self calibrate' normally on power up. There's a nice clear picture on the iPhone. Can't get the gimbal to respond to the up and down arrows on the app. in camera mode. Fpv mode is disabled. The Accelerometer button toggles normally but the tilt status bar on the right side of the screen remains grey with the topmost part red and won't move. Also noticed that when I move the left stick side to side (yaw) there is a slight movement of the gimbal. Tried reinstalling the app and have done both Phantom and RC calibrations. Any thoughts would help. Thanks!!!
