When you removed this app from your Facebook account, we disconnected every Facebook Page and Instagram account it had linked, and deleted the access tokens we held for them. Nothing further is stored.
Messages that had already arrived in a business's inbox belong to that business's own records and stay with them, exactly as a text message or an email would. To have those removed as well, write to support@saltservicesusa.com and quote the reference below.
