It is a requirement that your Instagram account must either be a professional account - so either a "business profile" or a "creator profile" in order for you to sign up with Make Influence. If you are already registered on the platform but switch your Instagram profile to a private profile, you will lose the connection and eventually lose access to your Make Influence profile.
It is also a requirement that your Instagram profile is linked to a Facebook page. This is not the same as a Facebook profile, but a page created through your Facebook profile.
