Can't Access Most Recent Facebook Post using Graph API

I have seen in most posts the common way to get the most recent Facebook post for a particular user is to query with limit=1 when sending a request (i.e., GET /{user_id}/posts?limit=1&access_token=...). When I make a Facebook post and do the request, the result is a post from a month ago rather than a few seconds ago.

Has anyone else come across the same issue?
