I have a personal FB and a business FB. Unfortunately I can only connect my business page (East West News Service), but when I go to connect a second FB account, it doesn't let me connect to my personal. It just connects to my business page for a second time.
I would like to inform you that you must be an admin of the page, profile, or group you want to connect. For more info, please check this article and let us know if that helps- https://adobe.ly/49elCiQ
