Yes! Happens often with the pages I manage. Would love to get some more insight about this from anyone in the group with some details. 

You’re not alone, @alexandrapotora

@alexandrapotora When I am the admin of a page, it always shows up for me (although I admit, I don’t look every single time).  But I’ve tested it with other accounts that Like the Page but aren’t admins and I do see that the post doesn’t show up all the time.  Just a fact of Facebook that Page posts aren’t showing up in the News Feed as much.
