Android Keyhash for Facebook issues

Question

I along with my friend are developing a App which has login with Facebook. We both generated our own key hash and gave it while generating the AppId.

The problem is I can sign in through Facebook but my friend cannot. The login works perfectly for me but my friend is unable to login.I use Windows and my friends uses a Mac.

Does Facebook take only one key hash? What may be the problem ?

Answer 1

Please check in the App Settings (in App Dashboard), that Sandbox Mode is disabled

Keyhash is not the issue if it is working for one user.
