When trying to style the New Universal Login page using the No Code Branding UI, there doesn’t appear to be a way to add a background to secondary buttons, resulting in a poor display for Apple’s social login button:
Is there any way to set the secondary button fill (or invert the Apple logo to white I guess) that won’t break from build-to-build of the Auth0 New Universal Login page?
Currently, we can not add background color to the Continue with apple button or update the color of the apple icon. If you need this feature, please community your use case with our Product team directly via the feedback page and click on the Vote button.
As a workaround to the poor display of the Apple logo issue. I suggest you change the widget background color to a lighter color.
