@arnydewatcher On my Win11 system, the problem seems much less acute than it still was a few days ago, even though I made no efforts whatsoever. I have not seen a notice about any Opera update, has maybe someone else noticed changes?

I'm having the very same problem in Opera under Win 11.

On my desktops, the workspaces are represented by extra icons in the left sidebar. You are correct that I may not have noticed changes in the background in the organization of bookmarks in the bar on top, but the left sidebar continues to look very notably different on the laptop.

@leocg But if it is done, the changes should be visible, including in the foreground. On the desktop PC that I want the laptop to become synchronized with, I redistributed my bookmarks into a number of workspaces. This change has not appeared on my laptop so far.

@leocg Thanks, that's easy. Except I don't see any synchronization at all, really. Earlier today I switched Settings > Synchronisation > Advanced sync settings > from "Do not sync data" to "Sync everything", and nothing happened or changed whatsoever.

Greetings,
to repeat the question (with one small clarification):

What do I have to do to get Opera to automatically log on to my Opera account and synchronize with my latest Opera session (tabs, passwords, favorites etc.), irrespective of which system that last session had transpired on? Ideally, if there is another active session on another system, it should recognize the fact and notify me accordingly.

A small step for you, very likely, a gaint leap for me.
Thanks!
