title: Google Analytics Custom Dimension is not being populated
body: <p>I have the following code in my application to set the Google Analytics Custom Dimension (dimension1)</p>
  
  <pre><code>  var membNo = '123456789';
          var gafile = '//www.google-analytics.com/analytics.js';
          var gaKey = 'UA-XXXXXXX-3';
  
          (function(i, s, o, g, r, a, m) {
              i['GoogleAnalyticsObject'] = r;
              i[r] = i[r] ||
                      function() {
                          (i[r].q = i[r].q || []).push(arguments);
                      },
                  i[r].l = 1 * new Date();
              a = s.createElement(o),
                  m = s.getElementsByTagName(o)[0];
              a.async = 1;
              a.src = g;
              m.parentNode.insertBefore(a, m);
          })(window, document, 'script', gafile, 'ga');
  
  
              ga('create',
                  'UA-XXXXXXX-3',
                  'auto');
  
          if (membNo.length &gt; 0) {
              ga('set', 'dimension1', membNo);
          }
          ga('send', 'pageview', location.pathname);
  </code></pre>
  
  <p>In GA, I have created the custom dimension (scope: user) 1 day ago but still cannot see anything coming through</p>
  
  <p>How long exactly is the lag before custom dimensions come through? I am confident I have set the diimension correctly before sending any <code>pageview</code> or <code>event</code> </p>
  
  <p>Thanks</p>
