Now when you need to generate an APNS certificate or renew the current APNS certificate you can now view the Apple ID you use for generating an APNs certificate, so next time when you renew the APNs certificate (which would expire in a year) you can look at the Apple ID used to generate the certificate from the portal.
In this way you can make sure you are using the correct Apple ID while renewal and prevent from re enrolling devices one by one.
