I\'ve been using instagram\'s real time push api (http://instagram.com/developer/realtime/) for a long time to get updates on a specific location. I use the highest possible
Had some communication recently with a contact at Instagram and he mentioned that Instagram's real-time functionality will be limited to only user subscriptions in the future.
Apps created before November 17, 2015 will continue to receive updates but are being sampled because of the load they are experiencing and the fact that the architecture used for this does not scale well. He also mentioned that, as a result, real-time subscriptions will be deprecated for Tags, Locations and Geographies.
The developer guides also have some information regarding this:
OLD: https://www.instagram.com/developer/deprecated/realtime/
NEW: https://www.instagram.com/developer/subscriptions/
I am using https://api.instagram.com/v1/users/self/feed?access_token=AccessToken&count=100 to get my feeds.
You might be missing count in your api or let me know which api you are using
