This is really strange to me. Why in the world would Comcast subscribers be locked out of HBO-Go for Android TV, but not on an Android phone, or XBox One, etc? What's going on here? Part of the HBO experience that I pay for is HBO-Go, so I feel like I'm getting ripped off.
Who's blocking this? Is it Comcast's doing, or Android/Google, or HBO? Really annoying. I know there are work-arounds (casting from phone) but I hate casting. I'd own a chromecast if I liked casting as a primary way to watch shows on my tv.
Because Comcast are assholes, that is why. It took them 3 years to finally support Roku.
