Remarketing list for Google Analytics

Hi,

question for Google Analytics experts:

I have created a remarketing list in Google Analytics and I would like to use this list for my AdWords campaigns. In GA it asked me to change the code for this remarketing to work, BUT I am using Google Tag manager so I can not change the code.

What I have done - I have turned on Display Advertiser Support in “Tracking Info”. It changed the code how it was supposed to, but when I click on “remarketing” it still asks for changing the code.

Warning: You have created at least one remarketing list, but have not made the necessary changes to your tracking code. Without these changes, your remarketing lists will remain empty and your ad campaigns may not run.

The list is not working in AdWords.

What could I do to make it work?
