Syncronizing Messages across devices

[rosenr9286t]

I use four different unlocked Samsung Galaxy phones, on Google Fi, depending on my activities for the day (S24, S24 Ultra, Z Fold 7, Z Flip 7). Until recently I would turn on the phone, go into Google messages, hit the icon at the upper right, go into message settings, then Advanced, and scroll to a selection for syncronizing messages across devices. My goal is to have all of my messages available. I only compose and send messages from the phone I am currenlty using. I'm assuming that feature was removed at some system update. Has it been moved? Is there a new setting that will provide that function? "Device Pairing" has been suggested,but it is not clear that it will display all un-deleted messages. Any guidance will be appreciated.
