I was developed a game by Unity 4.3 with Facebook Official SDK Plugins for Unity, and the game was released a few weeks, and work fine. However, i got a few report that players cannot login to facebook and got this error messenge. I tried to logout facebook and login again, this error happen.
I am very sure that my facebook app is NOT in sandbox mode and the option is YES in status and review, but I still get this error. any idea for me ?
Thanks you !
