Professional photographer and Phantom 4 Pro user here, with a new Mavic 2 Pro. In still camera mode I am familiar with changing the function of the right control wheel on my P4P controller by pressing it to cycle through the various settings, such as ISO, Aperture, and exposure comp. Nothing happens on the Mavic Smart Controller when I press the wheel. How do I engage the exposure comp feature? I need to use it all the time.
