Hello there.

We recently updated our production app in Google/App Store(s) and when performing a new Facebook login through a custom button in the app, Facebook is throwing a general error message telling us that the "Function is not available".

We don't have any required pending actions in our App Dashboard and the app is in production mode (live).

Have you ever faced this error before? I'm attaching SS (in spanish) from the Android Platform but, as I mentioned, it's also happening in iOS.
