Still haven't watched tho.
Edit
The biggest hit for cord-cutters will be from Apple TV, which simply is not supported. Same goes for Chromecast, too, though that's a little less surprising given that it's not quite as much of a remote control as you might think. Also not supported: The Netflix app on Windows, and browsers that use Silverlight. Though to be fair, you shouldn't be using a browser with Silverlight at this point anyway.
The good news is that you'll be able to watch just fine on Amazon Fire TV, Roku, Android TV, Android and iOS. (Android for phones and tablets is limited to Bandersnatch and Stretch Armstrong: The Breakout. You'll also need to be on the latest updates for apps, so be sure to check for that.
Winning!
