How do I add a comment to an assignment submission using the comment library in the Teacher app on my iOS device?
If you have added comments to the comment library in the web version of Canvas, you can leave comments using the comment library on student assignments. Comments can be added before or after grading a submission.
The images in this lesson are shown for a phone display, but unless otherwise noted, tablet displays mirror the same steps.
Tap the Need Grading status link .
Note: If you want to filter submissions by a different status, tap the Submissions link  and apply the filter in the Submissions page.
The student's submission is shown in the Comments tab and may contain comments from the student. If the submission was submitted multiple times, each file displays as a comment.
To view multiple comments, you can adjust the height of the comment window by tapping and holding the menu bar .
To add a comment, tap the Comment field .
Once you begin typing , if there are text matches, the comments display in the comment library. Tap the comment you want to add to the student's submission .
Note: The Comment field displays text only and does not include the Rich Content Editor for formatting.
If there are no text matches, no suggestions are available in the comment library.
