I saw an older post (2 years old) about Sling TV not playing after the Mi Box wakes up after going to sleep. Is anyone else still having this issue? Right now I have to reset the box every time (which drives my wife crazy!). I don't have this same issue with my Nvidia Shield.

I have to ask, did you factory reset after taking the Oreo OTA? That fixed most of my issues system wide, including buggy Sling TV
