In previous versions, turning on flying mode would lock the roll of the camera lens to the horizon. In the latest beta, the lens now rolls to match how you're holding the camera. This makes it very difficult to take level photos/videos
Enabling the auto-level behavior helps, but that locks the pitch as well as the roll. I still want to be able to pitch the camera up and down, just not have it roll to the side.
This could be fixed by either restoring the old roll-snapping of flying mode (maybe in 90° increments so it works with portrait orientation), or changing the auto-level behavior to only lock roll instead of locking roll and pitch.
