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.
I used to be able to change Pluto TV channels from my laptop. It could be watching Pluto TV on my TV through the ROKU, and change the channel from the Pluto TV web site from my laptop. I liked it because it was easy and convenient. Is that function still available? All I see is the whole Pluto TV on the laptop and nothing controlling my ROKU.
For more information about that channel's features and functionality, you'll want to contact Pluto TV support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
