I recently noticed someone I follow on instagram has not posted for a while, they're usually a regular poster. I went onto their profile to have a look and noticed a few posts that I've never seen and have not appeared on my feed. What does this mean? I know they've not blocked me as I visited their profile and saw everything, and I'm definitely still following them. It's a bit odd, just wondering what this means and if they've somehow restricted me from seeing their posts?
