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.
Yesterday afternoon the Prime Video channel refused to launch, flashing only back to the menu screen. After it still would not launch today, I unplugged the Roku TV for one minute. After re- plugging and powering on, the Prime channel generated a registration code which I activated on the laptop at Amazon. The channel now works again.
