title: Google Gmail - "The conversation that you requested could not be loaded"
body: <p>It seems like a link like:
  <a href="https://mail.google.com/mail/u/0/#inbox/1648ec7930317b4a" rel="nofollow noreferrer">https://mail.google.com/mail/u/0/#inbox/1648ec7930317b4a</a></p>
  
  <p>Displays 'The conversation that you requested could not be loaded'. The email with that id is clearly in the inbox (retrieved via <a href="https://developers.google.com/gmail/api/v1/reference/users/messages/get" rel="nofollow noreferrer">https://developers.google.com/gmail/api/v1/reference/users/messages/get</a>). </p>
  
  <p>Is this the correct way to link to an email by id?</p>
  
  <p>Edit: I should also mention that sometimes it works, sometimes it does not.</p>
