How do I change the language preference in my user account as an observer?
Canvas's default language is English, but you can choose to view the Canvas interface in another language.
Note: Instructors have the option to change the language preference for their courses. If you are observing a student in a course where the instructor has made this change (most often for a foreign language course), the course language will override your selected language.
