title: Unable to load BigBlueButton in iframe
body: <p>I am using a custom BBB installation for use in my Angular App. I am calling the join request in an iframe with <code>redirect</code> set to <code>true</code>. Everything was working fine with BBB 2.0 but after I have updated it to 2.2, I am getting an error <code>401 Unauthorised due to missing credentials</code>.</p>
  <p>However, if I make the same request in a new tab, it loads the meeting.</p>
  <p>There is another weird behaviour. It works fine even in an iframe on Chrome in Mac.</p>
  <p>What changed with 2.2? How do I fix this?</p>
