Contour for FireTV/Roku

I was in another State and a friend was showing me his Xfinity app on his Roku TV.

It worked perfectly.

About 4 years ago I posted the question when will we have it for COX.  

Why has Xfinity had this feature for a few years and COX stays behind in the Technology?

Can we get an update on when a well over due app for FireSticks/Roku will be available.

Thanks
