Why Does a Customer Name Show as “Apple User”?
If you see Apple User for a Subscribers Name

When a customer’s subscriber profile name appears as “Apple User,” it typically means they signed up through the app using Apple’s “Sign in with Apple” option.
Apple offers a privacy feature that allows users to hide their personal information, including their name and email address, which is why these profiles may display as “Apple User” instead of the customer’s actual name.
This behavior is expected and tied to Apple’s privacy settings chosen by the subscriber during sign-up.
