Such a shame. I've no app at the moment but am looking at my options.
The Nexus Player is 99% perfect as a TV box, but it makes no sense the things it misses; like YouTube subscribing. Why would Google cut such a feature from their app?
I have none of the network issues that others complain about and I'm not interested in pulling my phone out of my pocket, unlocking it then waiting for an app to load just so I can Chromecast something to the TV.
I think Google made a big mistake making the app selection so curated. Well it probably would be okay, if they were actually going to curate it on a regular basis and present now content.
