If I have the email app open and displaying the All Inbox I receive no notifications of incoming emails if the Pre is in card view or even if in another app. Seems I should receive notifications anytime I don't have the email app full screen. Anybody else experiencing this? I'm not positive but I seem to recall receiving notifications prior to the 1.0.3 update.
The only way to receive notifications is to either not be in All Inbox view or not have the email app running.
EDIT: this is happening if I'm doing something on the phone when the email is received. If the screen is off I receive a notification. As soon as I unlock the screen, and even though I have web fullscreen at the time, the bottom notification goes away.
