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'm guessing you're referring to the Testis Online game? My Tetris game has not been working for a couple of weeks now. When I open it up, the title screen just flickers. I was considering removing the app and reinstalling it but I cannot find it in the channel list so I would not be able to do that. I paid for the app, so I don't get why I still can't use it on my Roku. I've send a message to Tetris several days ago but haven't heard back.
