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

Firstly, why do you spam this thread with repeated posts?

Secondly, please READ before posting a question. All the necessary information is in the most recent posts, including mine which was the final one before your question. You didn't even go through that...

HOWEVER, I'll assist you with your reading issue: THE WORKAROUND is to sign out of your Microsoft account, because the bug was introduced with the unnecessary "workspaces" functionality... But, naturally, the synchronization with other devices and the ability to send pages to other devices' Edge installations is no longer available.

I hope this clears all your "doubts".

The engineering team is actively working on this. We apologize for any inconvenience this may caused and appreciate your patience.

Well it's now August 31st, 2023 and the problem still exists. How patient are you expecting us to be????

Fixed by logging out then doing a repair:

Settings -> Apps -> Installed-> Edge -> Modify

Worked for me.

as previously stated, logging out will restore the function but it will go away once you log in.

You are incorrect. When you log back in to your profile, the option is gone.

Microsoft: I was reluctant to fool with any new half-baked feature from Microsoft, and kept my stuffs in Favorites folders. Six months after I started using Collections the option to place multiple pages in a collection is gone. Can't drag n drop them either, half-baked and now broken for months. When will I ever learn? This workspaces scares me to death. Why rename, reorganize and make something new, when your basic features are still half baked? I refer to organize favorites which requires a 3rd party add-on to be able to do anything with organization and duplication of favs, but I digress.
