Terrible application - terrible notification system

I do not receive notifications during the day when I receive new emails. I have to open the app and refresh for new emails to show. I also receive notifications in the middle of the night that I have received a new email or have "# new emails" but when I open the app there are no new emails. POS app. What do you expect from something owned by RIM.
