A user tried to login to my app using Facebook login and they encountered the following error after being redirected to their native Facebook app: "Application Unavailable: The application you're trying to use is either no longer available or access is restricted".

I'm not able to reproduce it and I haven't found much online. The app is available since it's live under Facebook apps and it's being used by existing users. The only option would be that the access is restricted but I'm not sure why. I do know that Facebook launched a security update in March to "Use Strict Mode for Redirect URIs" by default, but this update does not apply to the Facebook SDK according to what I read.
