They updated the mobile app neverwinter nights, they’ve added a new free camera that allows you to adjust camera angle, can’t find it in the options menu ?
If it’s the same as Android,
Options > Input > Camera
takes you to the camera settings, starting with the classic 3 options dropdown.
Under Advanced you can remove the camera limits - perhaps that was what you’re after?
Thanks have to turn the Lock Screen off, adds a whole new dimension to this game.
