Answer 1

If the SNS endpoint is disabled after a while, that means your APNS certificate has some issue. Do you mistakenly use a sandbox certificate for prod, or visa versa? Do you have the right certificate and private key combo? See http://docs.aws.amazon.com/sns/latest/dg/mobile-push-apns.html for more information.
