Shout out to Google, they said in may they were adding a favorite tab to the live tv menu. They stated in may they were going to update the guide for YouTube tv. It's now July and my Google tv has not received any updates for these features.
Just got mine and it didnt fix my 2 year long YouTube Music Playlist issue. I know it wasnt a YTM update but no one really knows the cause of that issue either.
So glad I avoided getting this terrible device. The owners still complain about how bad it is.
I love the chromecast use it more then the sheild
