When a push certificate for an app is about to expire, you will receive an email notifying you that it's time to renew your certificate.
The email contains a link to our documentation on Renewing your Certificate, where you'll find the steps to complete this process.
Renewing your APNS certificate is a technical process. This is best completed by a developer or other technical resource.
You won't need to resubmit your app. The certificate is only used by our servers to communicate with APNS on your behalf.
