I've just updated my email address. Confirmation email sent by you to the new address and duly received. 3 issues:
1) It goes to spam in gmail (probably not your fault)
2) Gmail flags it as dangerous
3) The confirmation link you are supposed to click is not clickable. Clicking on it just selects part of it.
As a result my email address remains 'unconfirmed' - but appears to work.
