I sideload the HBO Go app on my Shield TV to get around the Xfinity lockout. Unfortunately HBO Go now forces the navigation to be locked in phone mode (probably to dissuade just what I'm doing), which makes reading the text very difficult.
Is there any way to force the GUI to take up the full screen? The video playback is fine.
