After setup of VIP to allow for authentication/authorization via push notifications, attempts to access a service that will require notification will receive a push notification. On iPhone 6 (and later) running iOS 10, when the user receives the push notification, selects "More Info", then on the subsequent page selects "Deny", access is allowed. In VIP Manager, the status code Status Code: 7000; Status Message: "Mobile push request approved by user".
This issue has been resolved in VIP Access for iOS, version 4.0. Please download and install this build after Nov 11th, 2016.
