The update for the Fold³ and Flip³ was rolled out in Korea and then for a short time paused to iron out some bugs.
Going from updates on sammobile.com and elsewhere etc it's been rolled out again.

This will probably have delayed the rollout timescale a little but I'd expect it to be hitting the phone's in the UK early to mid January 2022.
Other regions and branded phone's i.e one's supplied by a Network may differ @Ninjanut
