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 purchased Tetris in 2015, and it's the only video game I have (or have ever wanted to own). I like to play it once in a while, but now I find that it won't run on any of the three Roku 3 devices I use around the house. Is this a problem with Roku or with the game supplier? In other words, to whom should I address my complaint?
For more information about that channel's features and functionality, you'll want to contact the channel provider support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
