How get feedback from APNs when sending push notification?

This should work. You don't need to run this with every push request. Depending on how frequently you update, and the number of devices, you could set a daily or weekly cron job.

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.
