title: Hyperlinks within email body work in browser but not Gmail mobile app
body: <p>I've got a program that generates email reports and sends to certain recipients. The email contains a table of contents with hyperlinks to bookmarks later in the email.</p>
  
  <p>This works perfectly when viewing mails in the browser, e.g. on gmail.com. However, recently something seems to have changed in the Gmail mobile app, and my hyperlinks no longer work there.</p>
  
  <p>When generating the email, the link is of the form:</p>
  
  <pre><code>&lt;a href="section_1"&gt;Section 1&lt;/a&gt;
  </code></pre>
  
  <p>and the bookmark is of the form:</p>
  
  <pre><code>&lt;a name="section_1"/&gt;    
  </code></pre>
  
  <p>In the browser, the link URL appears in the form:</p>
  
  <pre><code>https://mail.google.com/mail/u/0/#m_3653008429050877336_1
  </code></pre>
  
  <p>In the Gmail app, however, the link appears in the form:</p>
  
  <pre><code>x-thread://-90370221/435827759917983#m_3653008429050877336_1
  </code></pre>
  
  <p>Any ideas what has changed, and how to make my intra-document hyperlinks work again?</p>
