As soon as I updated to 25.10, guest shares stopped working, and there is no longer an Allow Guest Access option in the UI I suppose this have been done on purpose, but I’m surprised it is not mentioned on the release notes. Is it intended to no longer being able to allow guest access to SMB shares…

Haven’t encountered that bug either, no smb related problems in my system :face_with_diagonal_mouth:

Plenty do, I see it being discussed on Discord as well.

I doubt engineering would have accepted the Jira tic…

It would be grear if at least we get a confirmation this is done or purpose or not.
