Hello, does this issue persist? If so, would you please file a bug report for tracking purposes? Thanks!

Hello @janeheffernan.

In our case, the problem is solved. The login started working again after Facebook reviewed our application and approved it.

We were getting this error in developer mode. When the application was in production mode the login worked fine. But in developer mode, it didn't work when we tried to login with developers and testing accounts.

I think that this issue is related to this one https://github.com/facebook/facebook-ios-sdk/issues/2148
