Just another one of those many reminders as to why users have to avoid using the old fashion web wallets that require one to sign up using email addresses. Users should also always back up their seeds just in case the service goes offline.
They claim to have fixed the issue - unfortunately for me - I'm still not receiving email authorizations to login to my wallet, which I haven't received for about 3 weeks now...
Did you back up your seeds? If yes, just import your account in electrum and ditch blockchain wallet for good.
