Over the past few days I've noticed the articles I share from my blog onto Facebook have not been shared properly, by this I mean I am the only one who can see the shared posts on the page. My other page admin cannot see the posts & neither can those who have liked the page. The posts have a "boost unavailable" icon beneath where it normally would say "boost post" . The older posts from a few days back & prior are still available to boost though. The recently posted links also say "Posted by comments" Rather than "posted by (admin name)" . Any known reason behind this issue?
