FB login blocked. App not set up: THis app is still in development mode, and you don't have access to it. Switch to a registered test user or ask an app admin for permission.

@Dhua-v At first you need to setup the application in ("https://developers.facebook.com"). There would around 10 steps to enable Facebook login. After completing the process you need to make the app from In Development to Live, For that you need to provide Privacy Policy URL & Terms and Privacy terms.

@Dhua-v After Completing all these process you won't get that issue ("#10").
