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.
Original roku movies are made into episodes that run fro 5 to 9 minutes long 1 hour and a half movie is now 15 episodes that run for 5 to 9 mins per episode. What a joke im going to cancel this channel
You cant really cancel it, its free - you can either not watch the content, or simply remove the app.
However, you should know that's how the content originally was edited for Quibi (the defunct streaming service for mobile devices that Roku bought the IP of).
The idea was that mobile users would be able to watch short episodes of 5-15 minutes on their mobile devices as they traveled, or during breaks at work/school etc.
The fact that the service was intended for and limited to mobile devices with very short episodes is arguably the reason it failed - nonetheless, thats how its content was originally produced, and thats how Roku bought it and is presenting it.
