I have Comcast/Xfinity. How can I add my favorite channels and/or the guide to my app or Roku? Thanks
Thanks for the inquiry.
For more information about that channel's features and functionality, you'll want to contact Xfinity support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
You can reach Xfinity support here: https://www.xfinity.com/support/
Thanks,
Danny
