When I open the Xfinity Home mobile app, it presents me with a Welcome! screen, with a button "Sign In" at the bottom. I click "Sign In" and go to a browser-like screen with the address "https://login.comcast.net" at the top, and a message "This site can't be reached" (including a REALLY long Greek-to-me (sorry, Greeks!) URL quoted). I have uninstalled the app, and reinstalled it, but end up with the same result.
