Getting issue on Android and iOS App with Facebook login

I’ve integrated Facebook login using reat-native-auth0. Both iOS and Android App is on production already, suddenly Facebook login is not working with both iOS and Android. when we debug the Android App and found the following issue “{“error”: “a0.session.user_cancelled”, “error_description”: “User cancelled the Auth”}” when calling auth0.webAuth.authorize API. I checked callback URL, tenant and domain all thing is correct. Any inputs this regard will be helpful.
