Thank you for reporting this issue to the Roku Community!
We understand that you are having issues with YouTube. We appreciate the steps you have taken. Could you tell us if the issue is only persistent with this app? If so, we would recommend the basic troubleshooting sequence below:
- Remove the channel: navigate to your Home screen, move to the right, highlight the app, press Star*, then select Remove channel
- Perform a system reboot: navigate to your Home, select Settings > System > Power (skip if unavailable) > System restart
- Re-install the channel: navigate to your Home, scroll and select Store, look for the app, then press Add channel
Additionally, please try connecting your Roku device to a mobile hotspot to see if streaming improves.
We hope this helps. Let us know if you have further inquiries.
