Thank you!
Hi @AnnC1955,
Greetings!
We appreciate you for sharing your concern here in the Roku Community. Have you already tried performing a system restart? If not, we recommend doing so since this is the common workaround for this. Just simply navigate to Settings > System > Power (skip if no sub-menu) > System Restart. After this, you can also unplug your Roku device from the power outlet for 30 seconds to 1 minute, then plug it again.
Kindly check to see if you notice any difference.
We hope this works.
All the best,
Kash
