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.
My newest roku I hadn't got around to turning the pbs app, just did without a hitch. You're entering it in address bar of the browser and not search engine like google? And the code is case sensitive. And do you have pbs account? You have to sign in, or start a new account.
