Facebook and Instagram are both owned by the same parent company: Meta.
In order to connect your Instagram account to third-party apps (like ours) you'll need to have added your Instagram account to a Facebook Business Manager.
There are a number of benefits to be gained from doing this:
Access to deeper analytics on your Insights Dashboard
Ability to run complex Fan Builder ads on your Instagram page
You can prove to us you are the owner of the Instagram page and start earning leaderboard points for it
