This app socks - iPhone 6S (AT&T); iPhone 7 (Comcast); Galazy S7 (Comcast) - same exact experience as everyone else has. No email updates; unable to connect - doesn't matter if they are on wifi, LTE, 4G. sometimes, simply closing and reopening the app helps, but usually the only fix is rebooting the phones - Trust me, Xfinity does not give a bleep if the app works or not - - - all they want is your money. The app is free - not skin off theie nose if you don't use it.
