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 use YouTube almost every day without an issue, so the channel is working. However, there are five different Roku models that use the number 2 in the name, and two of them are just called Roku 2. So we need to know what model number you have. If it's not the model 4210, it is very old, low on power, and YouTube just flat out might now work on it any longer. Google (owns YouTube) designs their channel to work with the latest, more powerful players.
