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 agree with Danny-R, it is much more likely to be a Pluto TV issue than a Roku issue, particularly if your other Roku channels are working. Mine just sorted itself out eventually, but may yet - as others have experienced here - begin not working again.
The US offering is very different to the UK offering.
I'm having the same issue, it started late last night and even after sitting overnight it still doesn't work. Works fine on my Chromebook but on the TV it crashes after a few seconds and goes back to home screen. Hisense Roku TV
The Pluto TV app was working fine on both my Roku TVs, until today. It tries to load, and you can hear the people talking on the tv channel from the app, and it still a black screen, showing it's trying to load the app, and doesn't, and freezes, and causes my tv to reboot. 🤬 Please Fix This!!
