Hi bkatrin,
Hope this helps?
I found out ( by testing ) that we need to delete the standard google analytics script ( like with some plugin to add the script or manually adding it ). Then only add the script into the cookie notice “Option to refuse third party non functional cookies”.
When I did that and looked in my Google Analytics real time visitors, I was not detected UNTIL I clicked my ” I agree” button.
So to answer your question, yes we need to delete the previously added scrypt, and ONLY add in the cookie notice!
