XR11 remote wont pair with the XG1v4-a set top box

Yes it XR11 orked fine with the old box and it also still controls the TV.  Is it possible that the new box will not accept more than one set of remotes.  In other words, the new buttons are poorly designed ( too small buttons) so we wanted to go back to the old XR11 remote.  Will it not take both sets?

I so, how to upair the new ones and go back to XR11?

word was "worked"   and also it should say "If so"

Try to Factory reset the remote you don't wish to use, then pair the one you do Vican75. This will walk you through how to do that https://www.xfinity.com/support/articles/programming-your-xfinity-remote. 

That link goes to a 404.  Can you answer the question about 2 remotes?
