Converting to a business account gives you access to UNUM Publish, where you can schedule and auto-post photos and videos on your Instagram Page. If you're seeing the error message below, it means you have added a Personal or Creator Instagram profile to UNUM or have not connected your Instagram Business account to a Facebook Page.
If you haven’t switched to IG Business Account, follow the steps here. Once that’s done, just click the "fix" button to reconnect your account. Just kindly make sure to authenticate via Facebook.
You can now create and publish content all you want with UNUM Publish.
These steps apply to all platforms (web, iOS, android).
