There seems to be a Mathematica glitch where all notebooks say “ This file is currently locked by another user. You are viewing this file in read-only mode.
If you begin editing, they will not be able to make further edits”, but I am the only owner of the notebooks and no one else should be able to interact with them. Clicking “Edit Anyway” then makes “Read only” say “syncing” and then “Read only” again instantly. How is it fixed?
