Just wanted to add that we’ve noticed the same problem and have been unable to fix it.
We added the GA script to the “Head” text field of the “Script Blocking” section and ticked “Enable to reload the page after the notice is accepted”.
Our GA traffic went down by >50% after doing this. Putting the GA script back into the header.php file of the site brings the GA stats back to expected levels.
I don’t for a second believe that over 50% of site visitors are rejecting cookie consent.
Any help with this matter would be appreciated.
