I am still a little upset about this. From my research it seems like HBO is being lazy in getting the apps out for both PS4 and Xbox One. Heck, Windows 8 doesn't even have dedicated app.
It's not too much of an issue, for awhile I would just hook my laptop up to my receiver and watch it through that. Then I realized I have a Smart TV with an app for it. Too bad because I cancelled my sub. because GoT is over and I watched all of Sopranos and VICE. Hopefully it will be up by next year. I don't really like using the Samsung apps as it is a little clunky.
