Someone I know but not a friend on Facebook has seemingly restricted only me from seeing things on her page. No message or friend button. Can't see her cover photo. Only see mutual friends. And only public or friends of friends posts from 2017 back. Other people also non friends can see all public posts up to yesterday. And a friend is tagged in two posts and I can't see them. Before 2 weeks ago I could see all of it public or friends of friends. I know there's a Restricted list but that I thought was only for people friended. It's weird.
