title: Changing Azure AD B2C Access Token lifetime doesn't work
body: <p>I went to my Azure B2C → User flows (policies) → A flow of type "Sign up and sign in V2" → Properties → Token Lifetime.</p>
  
  <p>There I changed the "Access &amp; ID token lifetimes (minutes)" from 60 to 15. Then I saved. I emptied the cache and refreshed the page to make sure that the value was really modified. </p>
  
  <p>Today, more than 24 hours later, all my access tokens still have a lifetime of 60 minutes. I don't get it. I got the access token directly from a brand new authorization code.</p>
  
  <p>Should I wait longer? Is it a bug in Azure? Or did I do something wrong?</p>
