I've got a Mi Box 3 and since the latest update (I've updated about 2 days ago) the 'Promotional Channels' keep enabling itself and showing "spotlight apps" on the homescreen, I think I have disabled it at least 5 times in the past 2 days and it's getting pretty annoying -_-
Just ranting a bit :p maybe someone has a way to actually disable it.
Google: Gee how strange, must be an accident...
