By default, consent pop-ups will start working from May 25th.
If you want to test how pop-ups work and you are from EEA, add ?showConsent=1 to the URL or check the "Change privacy settings" link that is provided. If you are not from the EEA, you can turn on "Test Mode" within the Consent Tool to check how pop-ups work.
It is possible to enable them immediately for a random percentage of users, or for all users. If you want to do this, please contact support or your account manager.
