certificate - If I revoke iOS Enterprise will the app still work?

Question

I am deploying my application via external URL. The application is installed on hundreds of devices all over the world using a Enterprise provisioning profile. The certificate is about to expire with a few days. My question is would revoking the certificate effect any of the existing users? I am aware that new users wont be able to install the application but what about existing users? Will they still be able to use the application correctly? If so do you know a time frame of how long Apple allows the application to work for?

Answer 1

Revoking the certificate will make any existing apps fail. I believe the certificates are checked when the device is rebooted.

You need to create another new certificate and update your user's device with a newly built app.

However, even if you don't revoke the current certificate, any existing apps will still stop working when it expires in a few days.
