Issue while attempting to update a per-app-VPN configuration

Hello All, I am currenlty on iOS version 16.0.2, and have begun seeing some unexpected behaviour when attempting to update a per-app vpn settings. The error I am currently seeing in the following.

`Error chain content: domain = NEConfigurationErrorDomain, error code = 2, description = "configuration is invalid: Duplicate perApp UUID" ( "n/a" ).

This is the initial profile I had sent down to the device (cut for brevity) and installed with no issues.

Profile was sent down with no issues.

When attempting to update the profile as I had done previously the above error occured.

  <string>globalhttpproxy.profile</string>

I had kept the same VPNUUID to prevent the need for me to reinstall the per-app vpns that had come down previously.

Has the rules around updating VPN/profiles changed with 16.0? Or do connectivity profiles now need to be removed before they are updated?

Kind Regards, Hamer
