logInWithReadPermissionsInBackground() user = null

[LeoDroidCoder]

Cannot log in when Facebook app is installed on device,
logInWithReadPermissionsInBackground() returns null ParseUser.
However, when debugging I see that authorization is actually successful and I receive facebook token and ID.

Here is the log:

I have the same problem! It only works when I'm removing my app from apps list in settings on Facebook. But when trying to login again it's not working (ParseUser is null)
