I have a ROKU Ultra which has the remote paired with an old TV. We purchased a new TV and I'm trying to pair the remote to control the new TV. The issue is that, when I go to Remotes & Devices >> Remotes (In Use), it just tests the current setup, but I see no way to change the TV that the remote is controlling. I've searched through the boards, and watched a video which showed a popup where a list of manufacturers was provided, but I don't see that on mine. Any idea how I can remove the current TV control so I can start over?
