When I start the device, it goes straight to telling me I need to update sling TV. When I go to update, I get a status bar that says "install pending" and it goes nowhere. What can I do? I've had this problem for a few months, and would really like for it to work. Also, if anyone has some helpful links on how to get the most out of my mibox, I'd be most appreciative. I don't know a lot about Android TV, but I do know I miss the dang cat channel.
