Enable Demographics and Interest Reports in Classical Analytics - google-analytics

Question

From a previous question I've come to know that I can't enable Demographics and Interest Reports with Universal Analytics tracking code. So I've created a new property for my account using Classical Analytics.
I've also set Enable Demographics and Interest Reports to ON under Property Settings and uploaded the tracking code to the desired site (it is a Facebook Application hosted on GAE if that matters, website link).
As adviced by Google I've changed my tracking code to use DoubleClick instead of Analytics:
ga.src = ('https:' == document.location.protocol ? 'https://' : 'http://')
+ 'stats.g.doubleclick.net/dc.js';
As far as I can tell, everything is configured as expected and my tracking id is receiving data.
Still, when I try to access any of the desired Demographic and Interested reports It says that my tracking code can't be validated. This is really weird since, as stated above, my code is already using dc.js.
If i try to click on the Validate tracking code button it basically tells me the same thing again:
So, am I missing something? Are we supposed to click Skip Validation?
p.s.: I've been struggling to get Demographics and Interest Reports to work for over a week (and yes, this is getting very frustrating...). Any help is highly appreciated.
Update
It is now possible to Enable Demographics and Interest Reports also in Universal Analytics [check this answer).

Answer 1

The data should show up in your reports soon (usually couple hours). Following up on Ishara's answer, I just wanted to stress that there is a requirement to update your website policy according to these instructions:
If you change your Analytics tracking code to support Display
Advertising, you are required to notify your visitors by disclosing
the following information in your privacy policy:
The Google Analytics features you've implemented based on Display Advertising (e.g., Remarketing, Google Display Network Impression
Reporting, the DoubleClick Campaign Manager integration, or Google
Analytics Demographics and Interest Reporting).
Visitors can opt-out of Google Analytics for Display Advertising and customize Google Display Network ads using the Ads Settings.

Answer 2

did you Enable display advertiser features .
" Enable Demographics and Interest Reports in the Admin interface: click on Admin (top-right orange navigation), then on "Property Settings", then on the checkbox below the Demographics and Interest section "

Answer 3

<script>
(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','//www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-xxxxxxxx-1', 'xdomain.com');
ga('send', 'pageview');
</script>
Please try the above code and Enable display advertiser features. Lets see after that.

Answer 4

Demographics doesnt work with Google Sites - yet
If your using google sites to have your website (which I am unfortunatly) your limited to your access to your source code, so you cant make the necessary adjustments to add the demographics (blacks and whites and girls and boys to your site) data to your analytics, you only get the Original analytics (visits per day etc.).
My complaint on the Forums
To enable demographics data, you need to put in that piece of code, well you cant edit google sites to add that code in. Also your "site manager" in google site only has 1 option related to Google Analytics, either turn it off or turn it on, and put in your UA_code.
Google Please fix this, why does your free and amazing Demographics Analytics service not included with your Google Sites package, kind of embrassing on your part (big guy)
