Notifications don't show unless the app is active

[PogoMips]

Hi,

I'm not getting any notifications (eg. email, facebook, whatsapp, ... ) unless the app is currently active.
I opened whatsapp and immediately got the notification for a five hour old message.

This applies to other apps as well.

Is there any way I can make the notifications pop up even if the app is not running?

I'm using a Nexus 4 with Android 4.4.2

Do you still have syncing turned on for those apps?

Sync settings as well as notifications are all activated
