Hi there, We use the “Sign in with Apple” in our app and web login. According to the“Sign in with Apple” policy, we should get the email either via private email relay service （if the user does not grant permission) or get the user's email (if the user grant permission). However, we found that we did not get the email for the user who use “Sign in with Apple” in the past month. We checked both frontend and backend from our side. It seems that Apple does not return valid email string. How we can report this issue to apple and fix the issue?
