I got very confused going through those old "friends" (now called followers). Don't know where I found it now, but I had a list of people who were following me. And I was clicking the OK box next to Follow or Following, thinking I was agreeing to everything. And then I discovered that a person would disappear from the list - which was not my intent. Then I clicked on Archived button and found that they were "dismissed." How do I get them back? And how does the follow/following - OK button work?
It's a notification that they have followed you. You've dismissed the notification by pressing OK to acknowledge it so it doesn't show any longer and goes to archive.
If you unfollow someone you can go back to their profile and follow them again. You might check in the archive if you somehow unfollow someone who follows you and shows up in the Connection Updates.
