Hello!
We are looking to federate our domain in Apple Business Manager so that our users cannot use their work emails as personal Apple IDs and to then create managed Apple IDs for all users in our enterprise. Currently, our Developers had Apple IDs created through App Store Connect. When we try to setup accounts in Apple Business Manager with Apple IDs for those developers, we receive errors about them already being created. Are these Apple IDs considered personal Apple IDs, or are they managed Apple IDs that do not populate in Apple Business Manager?
