VRRP sync-connection-tracking with multiple vrrp interfaces

I haven’t found any hint in the forums or manual pages yet and hope for clairification.
I have a pair of routers, each running 3 vrrp interfaces. Identical config.
I’m about to upgrade to 7.6 (from 6.49.6) soon to take advantage of synced connection tracking.

Do I need to enable sync-connection-tracking on each VRRP interface or would one suffice?

Thanks,

From the manual on https://help.mikrotik.com/docs/display/ROS/VRRP#VRRP-Connectiontrackingsynchronization:

If multiple VRRP interfaces are configured between two units, then it is enough to enable sync-connection-tracking=yes on one (preferably master) VRRP interface.
