X1 Stuck on Welcome

No I have not. I saw on the xfinity app that there is a known issue and that they are working on it. 

Yes, we are having a footprint wide TV service interruption with some networks. However, I would think the TV box would still activate for you. Please send us a direct message, so we can take a look for you. 

To send a "Direct Message" message:
• Click "Sign In" if necessary
• Click the "Direct Message" icon
• Click the "New message" (pencil and paper) icon
• Type "Xfinity Support" in the "To:" line and select "Xfinity Support" from the drop-down list which appears. The "Xfinity Support" graphic replaces the "To:" line
• Type your message in the text area near the bottom of the window
• Press Enter to send it

Well the actual issue was that I received a really old and useless box. A technician came in and was surprised to see the box and cable that I had received from xfinity. He gave me a brand new box and everything is fine with the exception of the tv asking me to pay for a subscription to a channel that is on my list. Either way I only have xfinity because I’m living in an apartment and I’m glad that I have directv at home. At least they send someone out to install the boxes at first. 

I'm glad the technician was able to get you taken care of, @user_6khf15. Please let me know if you continue to have any issues with your lineup. I know some accounts needed to have their subscription entitlements manually refreshed, but the process only takes a few minutes.

I’ve done a system refresh several times and I am still missing channels.
