Since Facebook owns Instagram, we need your Facebook permissions to share to your Instagram Business Account. First, you will need to switch your Instagram Account from Personal to Business. Next, you'll want to make sure that your Business Instagram page is connected to the Facebook page that your personal Facebook account is the administrator of (please see this article for the instructions on how to do it). Once this is completed, please connect the Personal Facebook account and the Facebook Page associated with your Instagram Business account to Ripl. You can connect your Instagram Business Account in the Social Media Accounts section under "Business Profile Settings."
