Since last update, on 3 occassions, the camera has been stuck facing straight down after booting the aircraft.  I have re started everything (aircraft, RC, Ipad) and the problem fixes.  Has anyone else seen this?  Also, I updated everything to the latest versions yesterday and today it told me I needed an update.  It downloaded something and indicated update was successful, but, I know I was already on the latest version?

Can you post a video clip.
Also if you have your C1 or C2 set to camera tilt then can you try to delete and reinstall the app and see if it persists. (sync your flight records before deleting the app)
Also, preform a IMU and gimbal calibration.
