I'm a new smartphone user and am having an email issue. I have a couple of Yahoo accounts that were configured using the default email icon. I set the frequency to Automatic (push), but even though an email has been sent hours ago (and i see it when looking at my laptop) it doesn't hit my smartphone. The odd thing is at times emails will hit the smartphone immediately, while other times it can take HOURS. Would greatly appreciate any advice on how to solve this.
