Hello, We are implementing the Apple Sign In on our website, and we are stuck and can't find any docs or issues on the forum about this. We generate the valid URL (https://appleid.apple.com/auth/authorize) to request the authorization code and the login part works flawlessly. The problem arrives processing the POST request from Apple (redirect_uri given by us). Its comes empty. No authorization code, no params, no nothing. Just a empty request. We just can't figure it out what is wrong here. Maybe a configuration problem? Any help will be greatly appreciated. Thanks
