I have had some Yongnuo flash gear for a while and it has been totally fine for what I need (manual flash, some simple off-camera triggering, etc.). I recently got ana Canon R6 and the on-camera flash with the YN560ivYN560 IV seems to work fine. I just went to try to change to second curtain sync, but when I try to go to the Flash Function Settings menu I get "This menu cannot be displayed. Incompatible flash or flash's power is turned off." Since the flash's power is not turned off, can anyone confirm it's just not possible to change these types of settings with this flash?
