EU Expressed Consent - As a user from the EU, the Cookie Consent Manager Modal pops up and forces you to make a consent choice. Non-essential tags do not fire immediately on first page load. You can Opt in to Functional/Advertising.
Zero Cookie Load is implemented for the EU examples. This means non-required tags (aka non-essential) do not fire immediately on first page load and drop cookies, rather we wait until the end-user makes a consent choice.
The user's consent choice is stored in Cookies and Localstorage objects, so you may want to start each test by using a private/incognito window or clearing cookies/cache in your web browser.
As you Opt-in to Functional or Advertising with the Cookie Consent Manager the related tags fire and you will see that code show below. Note Required allows fires and cannot be opted out of.
To understand how the code works, you can see the "View Source" of the page and review the comments for the different sections of code.
