Just got my Mavic Pro today and was just doing some set up in the app when I noticed the app will not let me assign actions to the C2 button.

Right now C1 is set to "Center Auto Focus" and C2 says "Not Defined"

Now if I tap on "Center Auto Focus" next to C1 I will get a pop up box that will allow me to choose different actions for C1, however if I tap on "Not Defined" next to C2 nothing happens. I do not get a pop up menu like I did for C1 and if I keep tapping on the box next to C2 then the actions for C1 will randomly change.

Is there something I'm missing here?

Is there something I'm missing here?

I doubt it; the process for customizing C2 is identical to that of C1 with the obvious exception of its selection being in a different place on the screen. If you don't get a popup at all when you press the C2 selection, I'd try rebooting the mobile device and making sure that the screen is able to recognize your touch at that location.

Thanks, I'll give that a try and see what happens.
