Xfinity blocking Google Firebase Domains

Has anyone tried to disable the Advanced Security feature ?, it's been buggy;

Hi EG,

Unblocking the domain on my own network isn't going to fix the issue for all of our users. I'm asking for this domain to be unblocked across the Xfinity Security product so that my company's user's can access and use our web application that is hosted on Google Firebase.

https://firebasestorage.googleapis.com

Additinoally, https://firebasestorage.googleapis.com isn't a website, it's a Google Firebase API endpoint. I forgot to include "https://" in my original example which has now been fixed, but the response, without including proper authentication headers and other bits, will be something like 

{
  "error": {
    "code": 400,
    "message": "Invalid HTTP method/URL pair."
  }
}

I thought I said that ?

EG, If we want to be pendantic, I pointed out in my original post that this was likely Advanced Security, but we don't really know for sure. What a mess. It would be immensley helpful to have a Comcast employee chime in on this issue. How do we make that happen?
