Running pre-purchase tests of XWD10...

While the Xara webpage on "Responsive Websites" ( http://xaraxone.magix.net/xwd10/ ) loads the mobile variant on my smartphone just fine, the XWD10 Free sample (R) template does not. I published it "as-is" as a test, but it loads the full browser variant on my smartphone.

What am I missing? Is there a special setting or another step I am missing before publishing?
(How do I ensure it loads the mobile variant on smaller screens as the Xara website listed above does?)

Please advise,
Thanks!
