I 'm seeing this issue too.
> Does the issue only occur on YouTube or across other channels installed on your Roku device?
All other channels work well. Only YouTube doesn't work.
> Have you tried removing the affected channel YouTube and then re-install again? If not, we suggest starting there. In some cases, removing the affected channel and then re-installing it may help. Restart your device before re-adding the channel back in to ensure the process is successful. We recommend doing this through the Settings menu by navigating to Settings > System > Power (If there is no Power submenu, proceed to the next step.) > System restart.
Tried. Didn't work.
Can you escalate this problem to someone at Youtube?
