It doesn't wake from sleep and you have to physically unplug it an plug it back in to fix this. Very annoying. Reading further, many people have had this issue for at least the last 2 years so there obviously isn't a fix coming soon. It appears to be a 50-50 roll of the dice and depends on your TV model. Other than this flaw, the device would be good. Doesn't work well for Plex app either, but I can't fault Amazon for that one as all other apps work fine.
