Have you raised a Feedback report? If not, please do so at https://www.apple.com/feedback/ then post the FB number here.

In all cases, you must raise the bug first, then you can, if you like, inform us on here, but we're just third-party developers like you. We have no input into when Apple deal with issues, and the best way to let Apple know there's an issue is to tell Apple about it by raising a Feedback report.
