After disabling offline_access and removing the app from app settings I no longer get an extended access token

You're supposed to take that 2 hour token and convert it into a 60 day one if your app needs it.

It seems if you set your app type in the Advanced Setting of your app at developers.facebook.com to "Native/Desktop" instead of Web, the extendAccessToken method currently returns a token that expires in around 1 day instead of just 2hrs.

I'm hoping there's a way to get a longer expiry than that, but no luck so far.

Looks like this was a bug that Facebook has since fixed.
