Xfinity apps are terrible

I hate to stomp on the original poster's thread, but since you asked publicly, I'll give you some details.  I have a thread going here: https://forums.xfinity.com/conversations/xfinity-stream-app/xfinity-stream-for-appletv-bug-this-device-can-only-access-xfinity-stream-on-your-inhome-xfinity-wifi-error-when-on-home-network/6782ee32121aae71d76b5ea6

Hello user_6b4c9b. Thank you for sharing your experience with the app and the missing downloads. I'm sorry for the inconvenience this is causing. Especially while traveling. People have busy lives, and if something is not going to work easily it's not something I want to deal with or use, but I know that you put time and effort into downloading those programs, so I want to help out in any way that I can to help make this a better experience. Can you please send us a direct message so that we can troubleshoot the issue with you and submit your experience to our engineering teams?
