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.
The AT&T TV website indicates that the AT&T TV app/channel is compatible with the Roku 3500x. But it does not appear in any search I do for available apps/channels on that device. It showed up immediately on another Roku I own (the 4620x). Is the info on the AT&T website incorrect or is there some unconventional way of adding it?
