Thank you, Student_ !!!
Comments and screenshot from Student_ are correct.
HOWEVER, the reason for SA's question in the first place is because he started by searching the Knowledge Base for something like, "how unfollow author I'm following" and the Knowledge Base instructs him:
To edit the users & authors you are following:
1. Click your picture at the top right of the screen
2. Select "Profile"
3. Click on the "Following" tab
4. Hover over any user's "Follow" button and click "Unfollow" to stop following that user.
BUT as SA told us, there is no "Following" tab in the "Profile".
I can't see ANY comments under ANY articles. What did I do? What SHOULD I do?
