I'm not receiving push notifications. What should I do?
Possible reasons include:
Push notifications have been disabled in the app settings.
In the side menu, tap "Settings" and enable the "Push notifications" setting.
Push notifications have been disabled on the device.
On the device, go to Settings — Notification Center ("Notifications" for iOS 6) — ICQ. Select "Banners" and enable all of the sliders (see the figure).
Push notifications are now enabled in the app and on the device.
In the app's side menu, tap "Settings", disable "Push notifications", and turn them on again.
