Going on 9 weeks & Advanced Security feature is either AWOL or when it decides to make it to the office to do its job which has been only 3 brief times & then it can be enabled.. No doubt devs & corporate staff/boarf don't have to use Xfinity nor its apps.. This app can't be compared to its cousin app on iOS which can be buggy but it's functional and can be counted. . Again, it's impossible that Comcast executive & upper Admin staff & their devs r burden with trying to use this dysfunctional pie
