title: Is it possible to force google amp html pages to refresh?
body: <p>Pretty sure i know the answer but cant find definitive yes/no.</p>
  
  <p>Is there a way e.g. api call to make a page stored in google's amp cache to force it to get new copy of that page?</p>
  
  <p>Editorial want to know when they update a page in cms that google gets updates too.</p>
