My Comcast email has showed up on my Droid just fine every night to be found in the morning - but this morning - nada, nothing on my phone, even tho Comcast account mail showed up in my PC inbox like always.
Refreshing the Comcast inbox on Droidy didn't load any new messages either. All settings appear to be the same as always...
Tried a reboot... Data Push is off, Fetch Schedule is set for every hour.
Are you accessing this via the regular email app or via Xfinitiy Mobile? If via the Xfinity app, try calling Comcast Mobile support at 1-877-599-1845. (I've been having problems with the Xfinity app for TV listings and DVR schedule controls.
