Take in mind that if there is an invalid deviceToken sent when sending notifications, Apple will silently drop every message sent. So I guess that the problem may be that you have invalid deviceToken (probably from previous cert) that are being sent with your current cert. Are you registering with the Feedback service?
Not sure what part made the difference but push notifications work again! Yay!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
