I don't know if it helps but I in my case it was enough to open the window two times, maybe with a fakeUrl for the first instance: js popUp = window.open (fakeUrl) popUp = window.open('https://appleid.apple.com/auth/authorize?client_id=' + clientID + '&redirect_uri=' + backEndURL + '&response_type=id_token%20code&response_mode=form_post&scope=email%20name', 'Sign in with Apple', 'height=500,width=400,left=600,top=200,status=no,location=no,toolbar=no,menubar=no' ) I know that is another workaround but it works to me.
