Team Projects - Can't Add Collaborators and Project Has Disappeared

I created a Team Project, but when I tried to add people I got an error  stating "People Graph service is currently unavailable. Please close the Edit Collaborators dialog and try again later." I ignored that and went on to set up the team project, thinking that I could add people later. But then, when I tried to add people in the Team Projects settings, I got a notice saying "Collaboration features are currently not available because you are disconnected from Team Projects." I exited the project to see if it would resolve itself upon restart, but when I next opened Premiere, the Team Project I had just created doesn't show up in my recent files! Does anyone know what's going on?
