Just purchased the Roku Voice Remote Pro. Successful pairing last night and watched a movie. When the movie was over I was unable to get any key/button to function. I paired the device again, but am unable to check the "I understand" box and am stuck on that screen. The voice function seems to work, but can't be used to check that one box. I tried turning the hands-free switch off, but no key or button works. Can anyone help?
