How do I view the Inbox in the Teacher app on my Android device?
Canvas lets you access your inbox on your mobile device so you can keep in touch with people in your course at any time.
The images in this lesson are shown for a phone display, but unless otherwise noted, tablet displays mirror the same steps.
Note: Unlike the web version of Canvas, you cannot view assignment comments in the Inbox. However, you can view comments in the assignment.
In the Dashboard, tap the Inbox icon.
The Inbox defaults to All Courses and displays all your messages. The layout is the same way as the browser version of the Inbox. Messages are arranged in chronological order—newer messages appear at the top, and older messages appear near the bottom. New messages are indicated with a dot that aligns with the course color.
Swipe the app from top to bottom to quickly refresh your messages.
