When I try accessing my Demographics and Interest Reports section in Google Analytics it says "Your Analytics tracking code does not include the necessary support for the Demographics and Interest reports.".
The built in GA code uses the older (and eventually unsupported) GA script from what I understand.
It should be a simple matter of converting your GA properties to Universal Analytics from the classic GA and then place the supplied script in your google analytics template, replacing the code that exists there.
Since I'm just a lowly end user of several copies of XenForo I would have no way of knowing for sure. I'm pretty sure eventually it will since Google is phasing the old code out.
