Cannot grant extended permissions

I am unable to grant extended permissions for this app, or rather get it to accept that extended permissions have been granted. (which they have). Everything at facebook looks good, the app appears to be able to do everything I want it to. (permissions are granted).

However, inside wordpress on the post page I see

Your app doesn't have enough permissions to publish on Facebook
Grant needed permissions now

I click that, a pop up flashes up and closes, the page refreshes and I am told.
