Chances are if you've been given access to a class team, your profile will indicate that you are listed as a "Guest". This is the typical access level for most students and should not be cause for alarm.

This is due to the nature of where your account may be hosted vs where the actual team class is hosted. As a Guest your privileges are limited, but you should never have any issues accessing chats, assignments, files, and video calls as designated by your instructor.
