I didn't say it was good so I don't know why I am being downvoted. I just figured that those who might for whatever reason have a Mi might want to know there is at least a goddamn update for it. No reason to downvote just because you don't like the Mi. It is not my choice either but I don't downvote someone trying to keep others informed.

And by the way, there is an app for Sling TV:
