On an annual basis, we receive notification from VMware Workspace ONE to renew the APNs for applications for iOS devices. It’s important to handle this at the soonest to ensure push notification messages go through VMware applications on managed iOS devices successfully.
Be sure not to confuse APNs for applications with APNs for MDM. The later is required to manage iOS with any MDM solution.
There are many other certificates that require an update on a regular basis. For more information, check out the link below or check out my post here.
We can confirm how many days before the APNs will expire for a list of applications by visiting GROUPS & SETTINGS -> All Settings -> Devices & Users -> Apple -> Apple iOS -> APNs For Applications.
To renew, first download the renewal script from the email received.
Then, take a backup of your Workspace ONE database and execute the renewal script accordingly. Notice the script name mentions SAAS.
Once the renewal script is executed, visit GROUPS & SETTINGS -> All Settings -> Devices & Users -> Apple -> Apple iOS -> APNs For Applications again and you should see the dates to expire have been extended.
