Okay so I have the 5d button set to "up-zoom in" and "down-zoom out". It's just not working. I can zoom in by cropping with two fingers on screen but the button won't control the zoom. I even tried all directions of the button with different functions and they are all working, so it's not the RC itself. I am under 4k resolution (tried in 2.7k and 1080) so I know that's not it either. I literally just went and exchanged my Mavic at Best Buy a few hours ago because I thought it was defective. Now the one I got is doing the exact same thing. Does anyone know why? Is there some other setting that may have gotten changed to cause this? Thanks in advance for any help with this.
