Advanced Security whitelist
We've had probably a hundred or more of the users of our software that are on Xfinity be affected by the Advanced Security feature blocking our software from performing basic networking (HTTPS or direct). This has been happening for months now. We have searched repeatedly for ways to whitelist our sites/software for Advanced Security, but have not come up with any way to contact or request whitelisting. (fantasygrounds.com)
How do we go about contacting someone at Comcast to prevent this from happening to our mutual users?
