Custom Domains with Sign in with Apple

I’ve successfully implemented Sign in with Apple on my app.

It works on the iOS app.

It works in the previewer in the app builder.

It does not work on the PWA version under my custom domain.

I have tried including the custom domain in the Apple Developer Identifier along with the ‘’ domain in both the domain and return URL.

When I attempt to use the sign in from the desktop browser I get redirected to an external Apple ID sign in page, but when hitting submit nothing happens. When I attempt to sign in using the PWA version on my iPhone the apple dialog modal pops up but hitting sign in just returns me to the original page.

Help please!

Hi Liam,

Can you post a screenshot of how you have set up the component? Obscure any personal or private info from the screenshot!
