I get this information when trying to see demographics in Google analytics. I'm using classic analytics.
"Your Demographics and Interest Reports have been enabled, but your Analytics tracking code does not include the necessary support to show them. Learn more about the simple, one-line, one-time change to your tracking code to add this support."
In the following link there is instructions to change a line in the analytics code, and since we're using your plugin it's not really an option. Is this something you are planning to solve in a future version or do you have any good solutions for me?
