Thank you Eduardo, You beat me to it. Apple was quick to approve our release with the fix, we should start seeing a decrease in such traffic. On Tue, Dec 20, 2016 at 2:29 PM, Eduardo Schoedler <listas@esds.com.br> wrote:

Immediately after being notified that our latest iOS release was causing problems with NTP traffic, we started working to disable the offending code in v9.45. We submitted a new mobile release to the Apple App Store earlier this morning for their review, which should disable these NTP requests. We are hoping Apple will be able to review this release in time before the holiday break, and we have stressed its urgency. When the release does get approved, we should very quickly begin to see a decrease in NTP traffic from our app as users start upgrading to the new release.

Just received update to 9.45.2.0.
