  <p>said:</p>
  
  <blockquote>
    <p>n Chrome's DevTools, cookies and other request headers are not shown in the network panel for cross-site subresource requests. 
    There are also issues with the DOM storage view, security panel, performance panel, and with scrolling over cross-site iframes in mobile device emulation mode, 
    <strong>all of which are fixed in Chrome 68.</strong></p>
  </blockquote>
  
  <p>But My chrome still have this problem.</p>
  
  <p>Could you give me a solution?</p>
