'Add all open tabs to collection' option is gone; when you right click on a tab it used to be at the bottom? Help?

I would say the lack of action or even interest by MS on this has pretty much provided an answer to your question.

Any resolution for this? or we stuck between a feature update forcing everything to Workspaces?

Exactly the same issue still around with no fixes. Unbelievable Microsoft Team.

It’s outrageous that you must be logged out to benefit from this feature.

Please could you an ETA on the fixes to be posted here?

Same exact issue here on latest Edge. Work profile is ok but personal doesn't show it.

Just as I'm trying to switch over from Chrome to Edge too and had this setup almost done.

If you're like me with over 400 tabs across many windows on Chrome trying to move to Edge, my workaround is using Copy All URLs & FreshStart extensions. I've set up some domains under profile preferences in Edge Settings > under Choose preferred profile for sites so when I copy and paste selected tabs or export/import with the other plugin/extension, it splits them to each profile. Only thing is, each window I had (8) was for certain research/projects so I've got that saved under FreshStart till this works then I can add each window as it's own collection but for personal profile mostly unless the groups autosave the color/name/window location which would kind of work the same way if/when restarting.

Sorry, but it is very likely that is not the case, if you read the previous posts, when you log back in, it will disappear. But thanks for your efforts.
