Mobile view is not being shown for embedded powerbi report

We have created a PowerBI report having both the desktop verion and mobile virson. Its showing desktop and pone view properly when we are testing at following sample site after putting correct information.

https://microsoft.github.io/PowerBI-JavaScript/demo/v2-demo/index.html

But when we open the website on mobile It is still showing the desktop version of the report. File version used of powerbi.js file is 'powerbi-client v2.5.1'.

The HTML and javascript used is provided below We are also appending '&isMobile=true' with embed report url. Are we missing any reference to show the mobile version.

      // Get a reference to the embedded report HTML element

      var embedContainer = $('#reportContainer')[0];

      // Embed the report and display it within the div container.
      var report = powerbi.embed(embedContainer, config);

      // Report.off removes a given event handler if it exists.
      report.off("loaded");

      // Report.on will add an event handler which prints to Log window.
      report.on("loaded", function() {
        Log.logText("Loaded");
      });

      report.on("error", function(event) {
        Log.log(event.detail);

        report.off("error");
      });

      report.off("saved");
      report.on("saved", function(event) {
        Log.log(event.detail);
        if (event.detail.saveAs) {
          Log.logText('In order to interact with the new report, create a new token and load the new report');
        }
      });
    });
  </script>
</body>
</html>

Solution

Issue is resolved. I was appending isMobile=true in embededUrl property of configuration.

report.EmbedUrl = report.EmbedUrl + "&isMobile=true";

We need not to append "&isMobile=true" explicitly, this parameter will be updated in the iframe url automatically.
