we have a lot of iPhones managed with ZenWorks Mobile Management and GroupWise Mobility Service.

Yesterday we wanted to install a ZenWorks Profile on a new iPhone Xs (iOS 12) but the profile installation always failed.
iPhones which were updated from iOS11 to iOS12 with installed profile works fine.

But new iPhones with iOS 12 cant be installed. Tried installing the MDM Profile on a iOS11 iPhone. Worked like a charme.

Our SSL Cert is SHA256RSA (Digicert -> RapidSSL).

Any ideas how we can go on with installing profiles on new iOS12 devices ?
