I have upgraded to Evernote 6.0.5. I am having trouble un-sharing a notebook with a former colleague. I can see the icon of the three people on the web interface but my desktop app does not show this. Although I can see who is sharing the notebook in the web app, I can't do anything else from here. In the desktop app, when I click the gear icon that appears when I hover over the notebook name, most options are greyed out. The share icon next to the gear icon gives me the option to start a work chat with one of my contacts but does not let me view who is currently sharing the notebook and ultimately unshare this notebook.
