Is there an update showing as available in settings then software update ?
If not then the update may not have been pushed out to your phone yet.
You could also try Samsung Smartswitch to see if you get an update that way.
Daily Driver > Samsung Galaxy s²³ Ultra 512Gb in Phantom Black.
The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "
