Sign In With Apple - Sign Up Not Completed

I'm using aws cognito for authentication in my app, and added the "Sign in with apple" identity provider. Not working at all by displaying "Sign Up Not Completed" error.

  • I am using custom domain in cognito..

I tried recreating the Private Key, and also recreating the Service Identifier. Nothing helped. Anyone experiencing anything like this?

I am having the same issue but my project is using Firebase for authentication, so it's probably not AWS or Firebase that's causing this.
