No new news except that iOS 11 coming soon. Sorry you are having to deal with the Apple iCloud account lockout issue. We do have a full team of development resources working on this issue.
It is difficult to determine the exact cause, as various factors seem to contribute to account lockouts and they can happen instantly or can be delayed by a day or more. Moreover, not every customer who performs the same pattern of actions is affected in the same way.
While detecting the precise cause is difficult, what is clear is that the issue is industry-wide and affects all monitoring services. We are working hard to evaluate potential solutions and will keep you updated.
However, our support team may be able to help so please call (800)245-8598 or email firstname.lastname@example.org.
