Did some tests with the DNT extension today just to find that even though I have the "halt load.." option selected, two tags still are loaded with DNT active. The number of cookies decreases from 26 to 17, which is fine, but I thought it should be even less of them, since DNT extension should block literally all tags?
(I also see our two syncronously loaded tags, but that is understandable.)
In our tests, DNT Extension was able to block GA. Because AppDynamics is not in our Tag marketplace we used a custom container instead and DNT was able to block it too.
We can take a deeper look at the configurations/templates and find out what is the issue. I suggest you contact your Account Manager with the account/profile in question.
