The Comcast XR15 remote will not select items on my new Samsung Q70 TV menu? I have Disney +, but have to get out my Samsung remote to select it. What pairing code can I use for the XR15 to navigate & select from the Samsung menue? It works everything else fine with the 12015 code. I'd like the XR15 to be the true universal remote for my very simple system- TV + X1 box. Thanks for guidance on this.
