I have several different providers for my MAIL (Inbox), but I am having trouble finding different ways on how to make it worn with daily updates (That means to for MAIL app to receive daily new e-mails in by updates or sync)...When I got this phone last December and it worked beautiful, but as of last week... somehow it stopped updating/refreshing... When I checked my Inbox via PC and there are always new e-mails in, but not on my phone. Why? Any advice? Thank you very much.
