I am having the same issue as Zee. I followed the steps provided by Sim2K (thank you) but still get the same message Zee quoted. I did follow the instructions provided by Google to add
ga('require', 'displayfeatures');
to the code but when I click on the “Validate Tracking Code” button in Google, it says that one line of code is still missing.
Any ideas?
Thanks,
Chris
Edit: This seems to be a screw up on Google’s end. If you click on Skip Validation, it will work.
