title: YouTubePlayerFragment on Android not showing ads - YouTube Android Player API
body: <p>I'm using the YouTubePlayerFragment to show YouTube videos on Android and the ads that are associated with them, but I have observed some <strong>wierd behaviour</strong>.</p>
  
  <p>It used to work fine on several devices (<strong>ads appeared</strong>) but not on others : the video player would work fine to play/pause video, but <strong>ads would never appear</strong>.</p>
  
  <p>Today, after building and debugging the same code, I noticed that the ads that used to appear on my device do not appear anymore! And my code hasn't changed...</p>
  
  <p>Do you have any idea what this could be linked to? Could this be linked to the developer API key I am using for development (limited number of requests for a certain device)?</p>
  
  <p>Cheers</p>
