We would love it if users could share directly to Instagram from SNAPPIC this would make it easier for us to track analytical data to provide better reporting for you and ultimately, for your customers. However, this is against Instagram's T&Cs which clearly state we cannot alter or re-engineer their API. 

A new update in December 2018 has now allowed some third party apps to integrate with Instagram but this does not help our case as we would only be able to post to business accounts and not personal accounts. This is a current restriction of the Instagram API unfortunately.
