I need Apple’s assistance migrating a legacy App ID prefix to my Team ID to add a native macOS app to an existing iOS app as a universal purchase.
Mac validation fails because the generated provisioning profile uses the legacy prefix for com.apple.application-identifier. This matches the issue discussed here: https://developer.apple.com/forums/thread/835497
However, Developer Support’s contact form rejects my prefilled Apple Account email with “This email address isn’t valid.” I checked my account details and retried in a private browser session. Phone support is unavailable.
How can I reach the Developer Program team to request this migration when the contact form will not accept my request?
