iOS APN Certificate fails to add or update after Apple introduced APNS2

Beginning on March 31,2021 Apple has changed the way that APNs (Apple Push Notifications) are being handled.

See the announcement from Apple:

Any existing and valid APN certificate will continue to work without interruption.  This issue would appear when an administrator is attempting the annual APN certificate renewal.  If an administrator attempts to import a new APN certificate, the validation for the new certificate will fail.  Even after a failed renewal attempt, the existing certificate would continue to be valid and device communication will still be maintained as long as the certificate has not expired.

The use of Apple's updated APN process is included in ZENworks Configuration Management 2020 Update 2. Environments running older versions will need to apply an official FTF prior to renewing or creating a new APN certificate. Applying this patch will not affect the end users or the existing APN communication, it will simply allow the administrator to create or renew the APN certificate successfully when necessary.
