No problems putting the Apple TV 4 to sleep (including turning off my attached television) prior to the update. After the update the AT4 box (and the attached television) keep turning on a couple of minutes after being put to sleep. Didn't touch the remote accidentally. Tried putting the box to sleep using the home button as well as going into settings. Had to unplug the box. Assuming it will be fixed eventually. Have seen a couple of other posts detailing the same issue. Oh Apple, why do your updates sometimes make things worse?
