I can adjust all of the settings on the 600EX-RT from my 70D but not from my 5D Mark IV; says it isn't compatible. I've spent the better part of an hour searching online to verify that (I'm guessing that the 600EX II RT does but not my model). I'm ok with just setting the controls on the flash myself but would like to know.
In advance - thanks!

The EOS 5D Mark IV should be able to make adjustments to the Speedlite 600EX RT. Are you able to enter into the external Speedlite control portion of the menu? Is the Speedlite connected to the hot shoe and powered on at the time you're attempting to make the adjustments?
