Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
For more information about that channel's features and functionality, you'll want to contact AT&T support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
See my post regarding xfinity..... this is a serious problem, only to tarnish Roku. QA is everything.... please implement a testing system / app review not unlike any other App Store. What you give us is only as good as who wrote the code.
