Add Push Certificate about to expire notification
Add a "when the Push Certificate is about to expire" event to notifications.
If the email of the AppleID used to issue the Push Certificate is not actively monitored, it is easy to miss the email alerts. And letting the Push Certificate expire can cause significant interruptions.
To prevent such interruptions, please add a "when the Push Certificate is about to expire" event to notifications, so that the alert can be sent to actively monitored email addresses.

This was added a while back we seem to have forgotten to mark it complete here. This option is now available under the Notifications section.
