Sorry guys for not updating currently on mobile....the app was side loaded and when you click on "play store" it takes you to the app but it doesn't let you download it. I was a bit surprised because it has never done that before. Maybe just wishful thinking and maybe jumped the gun. I had redownloaded and sideloaded the latest APK from XDA.
If you want a native app, check out Vue (my favorite), YouTubeTV, and SlingTV.
If AT&T doesn't want AndroidTV customers, then they don't deserve us as customers, imo.
There already is in Android TV version, just not for your device. I've had it on my Sony Bravia x850c for 3 years now.

Looks like an androidTV version may be coming
