My app was rejected by the Apple store based on the button styling / design of the Auth0 buttons in the Universal login.
My app at the time of rejection was using the Classic with v 11.24.1 lock js package.
Here is the message from Apple:
Guideline 4.0 - Design
We noticed an issue in your app that contributes to a lower quality user experience than Apple users expect:
- Your app uses Sign in with Apple as a login option but does not use Sign in with Apple button design, branding and/or user interface elements appropriately as described in the Sign in With Apple Human Interface Guidelines.
To resolve this issue, please revise your app to address all instances of this type of issue.
