Shield TV Owner here and use this device for games and streaming (inc Amazon Prime), just signed up for Now fibre with 3 Month trial on Now TV Pass. Very disappointed to find out this is not supported on Shield TV or my new Hisense 4K Smart TV, will be cancelling the Now TV Pass as I don’t want to buy another streaming stick/remote when the Shield TV & Smart TV should be enough. Yes people wont buy a Shield TV just for Now TV, they buy a Shield because it’s a very powerful games and streaming box that can handle pretty much anything you throw at it (apart from Now TV)
NowTV don’t support any Android boxes, including the NVidia Shield.
Just Android phones and tablets.
