I recently updated my Whatsapp to 2.8.6 and I'm not getting any push notifications anymore. So I restored Whatsapp back to 2.8.4 and the issue got fixed, when updating it again back to 2.8.6 and the issue is back. I have contacted the Whatsapp support team and they didn't give me much if any help on the problem.

This happens on both WiFi and Cellular networks. I'm currently on 5.1.2 iPhone 4. I don't have any 3rd Party Notification tweaks installed. If anybody has any suggestion please post it I would try almost anything.Thanks in advance.
