Flash wont work when using Live view display Canon 80D

[ayalaluisomar]

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.

Any tip?

At flash control settings all I get is "this menu cannot be displayed, incompatible flash---."

What kind of flash are you using?

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.
