Thank you for allowing us the opportunity to help. I would check to see if you are signed into your YouTube account. For example if you are watching something on the app and suddenly switch to live TV, then attempting to access last?
Djoseph, if you are using a Contour Voice remote, each remote is paired individually to one cable box. Please try a fresh set of batteries, then unpair and re-pair the remote to the cable box. If you have other TV's/cable boxes nearby that also use Contour Voice Remotes turn them off while pairing. Here is a link with information about pairing the XR 11 remote: www.cox.com/.../pairing-or-unpairing-the-contour-2-remote.html Please let us know if this helps.
