title: Can't view adcampaigns, even with ads_management permission enabled
body: <p>I am working with the Facebook Graph API using an account that manages a few other accounts. I can perform most operation just fine, such as adgroups, stats, etc. However, when I try to call adcampaigns or adcreatives I get the error message:</p>
  
  <blockquote>
    <p>(#294) Managing advertisements requires the extended permission ads_management, and a participating API key</p>
  </blockquote>
  
  <p>This also happens in the graph explorer. I generate a token and I check the ads_management permission and run the same operations, but I get the same problem. I can call adgroups, adaccounts, stats, etc., but I cannot call adcampaigns or adcreatives. Does anyone have any ideas as to what I'm missing?</p>
