It is confirmed that we are having an email issue. A ticket has been opened and we are waiting for an update.Is email for me too. I'm watching a thread in 911 and no email notifications, even though I've been mentioned in a few posts. I haven't had any emails since the update but the forum alerts (the bell up top) are fine. I only have email alerts selected for mentions, profile messages and the one thread.
Edit: watching this thread too now as a test.
