Hi @19491,
Welcome to the Roku Community and thanks for reaching out.
A simple restart may help most at times, you can unplug the device from its power source and then try again to see if that helps. If the problem persists, you can perform a factory reset on the device to verify if this is a device issue. You can check it for more detailed instructions: How do I factory reset my Roku® streaming device?
With more information, we'll be able to further look into this.
Thanks,
Rey
