Hello
Excuse me for my English

I read earlier this forum and did not find a clear answer.
I have a phone with Android 4.4.2 and for anything I can not get AquaMail to display notifications for new mail.
I checked where possible and certainly set to sync, and of course it is. The roadmap also all set. It IMAP protocol.
The application system works as it should and shows the notification as it should.
AquaMail need because of the identity (bought versions of Pro). Bit of a pain to use two e-mail programs at once.
Is there a mistake? Or maybe not everything checked?
EDIT tux:
Notifications act only as the application is opened and not closed. Should not they work notice how the application is not running?
