I succeeded in using "usePopUp= true''' on the website and in the iOS mobile app. However, I could not do it in the Android app. The error is: Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://www.example.com') does not match the recipient window's origin ('https://appleid.apple.com'). The apple popup is shown and after hitting the "Continue" button, it does not show anything, and clicking the "Continue" button again, it shows "Try again later". I could see the request "https://appleid.apple.com/appleauth/auth/oauth/authorize" was also sent. In the subdomain and domain tab in Apple config, I set: "www.example.com" and the return URL is "https://www.example.com". What did i do wrong here?
