Yongnuo/600ExII/R5C combination

Friends.
I am trying to use this combination. I have managed to get sync between the trigger and the flash. (Green lights are on). But, when I click on the camera, the flash does not fire. (When I press the flash button on the flash, it fires.) What am I doing wrong? Or is this problem related to the new flash mount? Thank you in advance!

I figured it out. The camera needs to be in mechanical mode, not electronic shutter mode. Stupid me!

But, does anyone know why the flash does not fire when the camera is in electronic shutter mode?
