Custom Email Domain Problem
After I upgraded my iCloud+ account from 200GB to 2TB, managing the email addresses in Custom Email Domain doesn't work anymore.
In iPhone's iCloud section, I can only view the existing email addresses. I cannot add new or remove the existing email addresses.
On the iCloud web, I can only delete but cannot add new email address.
Anyone had this issue before? Who should I reach out to resolve this issue?
Thanks
iPhone 14 Pro
