Sync not working across to android phones

Just got a new note 20 ultra upgrading from a note 10plus. Created a sync chain between the 2 hoping to transfer all bookmarks and open tabs. But it hasnt worked.
This is the note 20

This is the note 10.

Kinda figured it out. Had to reload all the tabs i had open on the old phone and then they would sync into the recent tabs menu on the new phone.
