I am trying to set up the Sleep Mode on the Moto X (2nd Gen). I enabled it last night, set up my favorite callers who can still get through, etc., but a couple of hours into my beauty sleep, I got woken up by the loud ding-ding-ding of an incoming email notification. The rocker volume was set to high. Do I need to reduce the phone volume to not be disturbed by incoming email notifications? If so, that kinda defeats the purpose of the Sleep Mode. I thought that Sleep Mode should disable all incoming notifications other than calls from favorite (starred) callers. Or am I doing something wrong? Thanks! Just picked up this phone on Black Friday, loving it so far and trying to get it set up just right.
