I'm having an issue about connecting the Instagram profile, while setting a brand new Facebook Business Manager. As long as I want to connect my only FB page, the system recognize it is related to an existing IG profile, but when I login it appears the following message: error_type: "OAuthException" code: 400 error_message: "Invalid redirect_url". I tried both on Firefox and Safari, but the result is the same. Anyone can help me?
