Can't fix my harmony remote to add xfinity guide and other pairing options

I’ve paired my harmony remote and have enabled buttons to open up certain apps and change colors and other cool stuff but the one part I’m stuck on is combining my comcast Samsung v2 x1 remote with proper functions like guide and select. It seems like it’s only slightly paired with the tv it self. I’m trying to eliminate all remotes and my wife likes the harmony remote so I really want it to function right. Harmony has a guide button but I can’t get it trained. It just sits there when I try and says unsuccessful. Help please any ideas

This is not an ST issue. You will probably get better results in Harmony forum/ help . Sounds to me like it did not get the right codes for your box.
