问题
All of a sudden posts on certain public pages seem to be missing when I try to access them with the Facebook Graph API. I know that they exist, I can see them in the web interface. Besides, I have downloaded them a couple of weeks ago.
If you use the Facebook Graph API Explorer and try out this query:
TeamStronach/posts?limit=50
you will get the posts of the page. If you jump back a couple of times (by clicking the link in the next field of the JSON result at the bottom) you will see that the posts end with 2017-01-01. All posts before that date do not exists, even though they are visible in the web interface. It's a couple of years that are missing here.
I encountered a similar behaviour with this page:
Sozialdemokratie/posts?limit=50
The entire year 2016 is missing! There is a jump directly from 2017-01-01 to 2015-12-31.
Does anyone know why this happens or how to solve it?
