Well its good news, BUT I would have thought an email to all subscribers saying that a fault has been identified, a solution should be available within X weeks after extensive testing.
This would show that we are valued as customers, and we have an organisation that updates their clients, because they are valuable, which we are. Just leaving a known issue that causes anxiety to so many with no assistance or even acknowledgement of it is poor service. Microsoft could better I am sure. Engage with your client base would be a good start.
