Pairing Mobile Device to TV through X1

So, the X1 "Easy Pair" platform says to pair my mobile device using X1 Photos Mobile - Easy Peazy.  Except as noted somewhere here last summer the app was deactivated March 2019.  So the big bright print on the FAQ for Easy Pair instructs us to use a deactivated app to pair mobile devices.  Right.  So, Comcast...  ?

Is there a solution? Or is Easy Pair just a dead feature itself?  I mean, I know I can cast to my tv using a multitude of other means but it is kind of ...  shady (?)  to offer this big ole feature that is no feature at all. Unless of course, you DO have a secret app by which people can utilize the touted feature? #baitandswitch
