I have just received my confirmation e-mail, over 2 hours after creating my new account. For my initial attempts to set up my account I rejected the advertising/marketing cookies and did not get any confirmation e-mail. A few minutes ago I used a different browser and accepted all cookies. I got my confirmation e-mail within minutes.
This may have been just a long wait, or it may have been due to cookie settings, but there may be something there that helps people still waiting for the confirmation e-mail, as I had been.
