Still receiving push notifications after revoking APNs cert

Question

My APNs cert is expiring soon so I revoked the APNs cert (just to make sure everything is working fine). But after 30 min I am still receiving testing push notifications. Is it because of Apple's cache? How long will it last?

Answer 1

Your old certificate is not expired yet from your question. So If your server uses the same cert, your existing iOS application will receive push notification. You should replace the old cert with new one.
