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).
