We are in contact with the 3rd party to assist them in making the necessary fixes, and are also pursuing potential workarounds to address the configuration issue in case those are needed. At this point in our investigation, we believe this is responsible for most of the reported incidents.We are investigating additional potential root causes for the remainder of the reports.A small (low single-digit) percentage of Windows Phone customers have reported being affected.We are continuing to investigate this issue and will update with additional information and guidance as it becomes available.
