Lets asume I fetch recent user media for a tag... And that I am able of storing in a database the information that it is returned to me by the API.
The media ids are something like [0-9]+_[0-9]+, and lets asume that one day later, I want to fetch only new data, so I order the media, that I stored in my DB, by instagram's created time, then I select the one that its the newest and grab its id something like '121231232213123_12312312312'.
Then I use that Id as the max_id attribute for the API endpoint https://api.instagram.com/v1/tags/{tag_name}/media/recent, I would assume, that I would get new user_media or an empty array if no one had upload anything.
The thing is that I receive all the same data, its like if it not filtering my results nor using the max_id.
is this correct behavior or should I do something else?
thanks,
ps: I posted this same issue also on google groups:
