Welcome to the Roku Community!
I'd be happy to take a closer look to see how we can help get you up and running.
A few questions here to better understand what you're experiencing:
- Does the issue only occur on Youtube or all channels on your Roku device?
- Are you being prompted with an error message?
- How long has the issue been occurring?
- What troubleshooting steps have you taken so far to try to resolve the issue?
As a first step, could you try removing the channel that you are experiencing the issue with from the Roku home screen? Then, disconnect your device from power for a minute. Plug it back in, then try to add the channel back once more and see if this clears up the issue.
