How do I like a reply in a course announcement as an observer?
You may be able to like replies posted to course announcements. Instructors can choose to allow all course participants to like replies, they can restrict liking to users with grading permissions, or they can turn off the feature for an announcement.
If the steps in this lesson do not match what is displayed in your student's course, learn how to like a reply to an announcement in the Announcements Redesign interface.
Locate the reply and click the Like icon.
