Having a really annoying issue with my Gmail app. When I open it, it doesn't show any new emails have arrived. I have to swipe up/down on the screen to refresh and then new emails populate. So say you're waiting for an email...if you open the app, darn it hasn't arrived yet cuz you're looking at your Inbox and there's nothing new. But oh you randomly swipe the screen and poof, emails magically apoear.
