Can't find a setting to enable external flash to work when I'm using the Live View display on my Canon 80D. if I turn off the live view display all flashes work perfectly.
At flash control settings all I get is "this menu cannot be displayed, incompatible flash---."
Im using the Godox 850IV and other remote flashes.
I just get this answer and it worked.
When using LiveView, Flash shooting will automatically be enabled with an ETTL flash in the hot shoe. With a Manual flash, you need to go into the menu and disable “LiveView Silent Shooting” by selecting “Disable” (not Mode 1 or Mode 2)
I wouldn't ever guess that was good solution.
