That's what doesn't make sense to me, I have it on my Sony blu-ray player, but not my ATV. I know this has been discussed ad nauseam, but I just think that Amazon content and Prime program is more of a profit center than fire tv products. They should make it available for every device they can.
Clearly they are. It's on many many devices. The million dollar question is why isn't it on Apple TV. Opinions seem to vary on the why.
