i'm having same problem, exporting my SCV file from squarespace to facebook catalog manager, and uploading it to facebook, giving errors of product id and basically the fields are not compatible , i can only product tag if i add in the items AGAIN manually to the facebook catalog manager, this need to be fixed, or squarespace need to tell me it just does not work? did it ever work? why is it not fixed ? when will it be fixed? i'll be looking to dot he same thing on PINTEREST too to drive traffic back to my website. what's the point of having a website if its a stand-alone website that you cannot upload your inventory to facebook ? so i can sell on instagram, can someone send me links, documents and can squarespace reply to this message please too.
