Comcast Put Xfinity Stream App on the Google Play Store for Android TV Already!!!

Why after all these years has Comcast refused to put Xfinity Stream App on the Google Play Store for Android TV devices????????????

I own a Shield TV and Onn4K Plus and Xfinity Stream is NOT on the Google Play Store.

Why does other TV devices like Apple TV, Roku, FireTV and Samsung TV's have it but not on the very popular Shield TV and Onn4K Plus?

Comcast I beg you from the bottom of my sweet heart PLEASE put the brand new Xfinity Stream App even with all it's missing features on the Google Play Store!!!!!!!!!!!!!!!!!!

We have been asking for this for many many years so why do you refuse????????????

What is the issue?

Thanks and have a nice day. :)
