title: Session Cookies expire way sooner on mobile than on desktop
body: <p>We're using session cookies on our website. After 8 hours they expire.
  On a desktop browser (Chrome, Firefox, Edge,...) this works just fine.</p>
  
  <p>But on the default Android browser (Chrome) they expire way sooner. (2 hours)</p>
  
  <p>However we make no distinction between desktop or mobile when setting our session-cookie.</p>
  
  <p>Is this default behaviour? And how can we extend the session time on a mobile browser?</p>
  
  <p>(Tested on Android 7.1.2 with Chrome 60.0.3112.116)</p>
  
  <p>But other users on other mobile devices are experiencing the same issue.</p>
