When I am in the work tab and using a personal view, it looks like I am unable to add new work items.  I am able to click the button for new work in the top left corner of the table, but after I select a user story or bug, I then see the message "The link you followed wasn’t valid for your session. Return to the previous page, refresh it, and try again."  I see someone reported a similar issue, but I only have a problem in the personal view, and not the standard view in the work tab.
