Hi, tks for the support..
Please your plugin works well for collecting some cookies variables(pro) in this use case : i go directly or navigate to the landing page where the iframe is embedded with a form.
I mean the cid (client id i scrape from google analytics cookie) and user status (logged or not from wordpress) works fine and are populated with the hidden fields of the form.
But as soon as i come from a referrer with the same but url tagged with utm variables (for google analytics), the cid is not populated anymore such as :
http://www.mywebsite.com/malandingpage/?utm_source=Ga&utm_medium=Affil&utm_term=gtm&utm_content=sponsored&utm_campaign=summer2016
Of course, each test is cleaned up from cookies between each session.
Thanks for our help !
