XR15 remote - pairs with one Samsung TV but not another

I just got Xfinity set up today.

I have 2 Identical Samsung televisions. The X15 remote in the living room pairs and controls the TV fine.

The one in my bedroom, while it says it successfully pairs, will not control the TV at all. I can't figure out why as they are both identical televisions.

Also, I can't find a way to pair it with my Vizio sound bar.

Any suggestions?

Thank you
