I cannot figure out why the app will not attempt to auto sync. I've tried all different schedule options but none seem to work. I'm using a POP3 account. I have the free aqua mail on my tablet for the same account and it works just fine. I paid for the pro version on my phone (Razr Maxx) because I liked the app so much on my tablet but now my emails don't come thru unless I actually open the app and press refresh. Please help.
