title: Requesting additional FB permissions on an existing/approved app
body: <p>I've got an existing app with a few thousand users. I'd like to add extra functionality which necessitates requesting new permissions.</p>
  
  <p>Will requesting the new permissions (essentially making a new review request) move my app into unpublished status? Or will it continue to function with the existing granted permissions while login review takes place for the new?</p>
  
  <p>Might be a stupid question - but didn't see any documentation on it and want to ensure I'm not cutting off service for the 4-5 days that it takes them to review/approve/possibly deny.</p>
