An issue with Apple Social SSO Sign-up

When signing up for the first time using an Apple account, it doesn’t work with an error

Callback handler failed. CAUSE: access_denied (Request failed with status code 400)

But, logging in for an existing account that matches the same Apple ID email works fine.
The return URL which I use in the Apple service ID account → https://YOUR_AUTH0_DOMAIN/login/callback
Thanks for any help!! :slight_smile:
