Agorapulse is an official Instagram partner, but sometimes we're not able to provide certain features for Instagram users. The reasons for this may vary, but some features Instagram prefers not to make available through their API, meaning no 3rd-party services have access to them.
Here you can find all the info about Instagram Content Publishing limitations.
Below you can find the list of features that have not been made available through the Instagram API (yet). As soon as they are made available, the Agorapulse Dev Team can start to work on them:
