- Sign in with Apple is missing, hidden, or broken.
- Apple login does not create the same account graph as Google.
§ 03What to inspect in your project

- Sign in with Apple capability and entitlement
- Hide My Email handling

Hello App Review, We added Sign in with Apple on the same screen as our other login options. Existing users can bind an Apple ID from Settings if they already registered with [Google / email]. Review can use a fresh Apple ID on the login screen. Hide My Email is supported. Thank you.
§ 05Should you appeal?
Appeal only if you already offer Sign in with Apple equivalently and the reviewer missed it. Attach a screenshot of the login screen.
