I'm compiling a URL like
https://graph.facebook.com/v2.5/<campaign id>/insights?since=2015-08-10&until=2015-11-13&time_increment=1&access_token=<valid token>
This query, even in GRAPH explorer, gives back data which is obviously outside the given date range. Putting something weired as "until" date causes an error, but I do not get it working in a way, that the result is within the given range. I.e. I get rows for "2015-04-21".
What am I missing?
