title: Why rewarded video ad type is not showing in create placement at Facebook Audience Network?
body: <p>I have a gaming app and  I am using admob for mediation. For banner and interstitial ad I am using admob and Facebook Audience Network. But for rewarded ad I want to use Facebook Rewarded Video ad too. But when I am trying to create a placement there is no reward type ad. It is showing below ad types
  1) Native 2) Banner 3) Interstitial 4) Medium Rectangle</p>
  
  <p>No reward ad unit. What is the problem?
  Admob doc showing FAN supports rewarded video
