Testers not able to login into the Facebook integrated Android app

Question

I have integrated Facebook in my Android app. I have added my friend as a Tester for the app. I think he has not accepted it and I find Pending near his name. When he tried to login with his facebook id, he couldn't login whereas I could login with my id as I am the Administrator . I had never enabled or disabled the Sandbox mode and now also I am not able to enable or disable it. My Single Sign On mode is on. Can anyone guide me how to fix it and should the person added as a tester accept the request and then only he will be able to test the app?

Answer 1

He'll go to developers.facebook.com/requests and accept the Tester role. Then he can login.
