So! Currently testing 4 Canon Rebel SL3 on one tripod, all aiming at me. While on the “Cameras” view in the “Capture” Tab and live view turn on, I can only move one AF box in the top right camera screen box, and it moves the rest of the 3 cameras AF box as well and not in sync to each other.
When I try to adjust the AF box on the other cameras, the AF box wont move to the new position I dragged it to and snaps back to the original location.
How can I adjust each individual AF box for each cameras WITHOUT doing it 1 at a time in “Single” Active Camera mode?
