The couple threads on this I saw said there is no solution other than to manually resort the 1000’s of bookmarks you have. A “old to new” or “new to old” sorting option would be extremely helpful here. Brave is now ruined for me.
Brave hasnt fixed this CATASTROPHIC issue that has persisted for more than 5 years.
I did find an extension called Sprucemarks which sorts things pretty well, though not 100% back to normal.
Brave has been disappointing in this regard.
