I'm trying to collect all the posts of my company page with this kind of query
https://graph.facebook.com/v2.2//feed?limit=250&fields=id,type,status_type,comments{id},likes{id},shares
Problem is that I'm not collecting all posts. I will have a better result with limit=20 and some time with limit=100
Most of the pages (from the pagination mechanism point of view) will not have 100 items.
I know some posts may not be exposed because of privacy settings. My issue is that a call with limit=20 is not returning once going through pagination the same amount of data as limit=250.
How could it be?
How providers of Facebook Analytics can garanty the quality of data they collect ?
