On January 28, 2020 Apple released iOS update 13.3.1. New restrictions introduced in the update adversely affect the biometric support introduced in Mobility version 11.50. NetMotion is releasing Mobility 11.72 for iOS—disabling biometric support as a temporary fix to prevent users from experiencing connectivity problems until Apple resolves the issue or a workaround can be implemented. Note: 11.72 for iOS is narrowly targeted at iOS biometric support. It does not change VPN authentication.

As an administrator, you have two options depending on whether you want to upgrade to the latest version of iOS, or if you want to maintain biometric support.

• If you want to continue to use iOS biometrics on your clients, you must not upgrade these devices to iOS 13.3.1. Additionally, you must not install the Mobility 11.72 iOS client, which disables support for iOS biometrics to prevent connectivity problems.
• If you must upgrade your devices to iOS 13.3.1, or you cannot control how users upgrade their devices, then NetMotion recommends that you disable the Mobility setting “Authentication – Biometrics” and install the Mobility 11.72 iOS client prior to upgrading to iOS 13.3.1.

Users with Mobility devices already running iOS 13.3.1 that are also configured for biometrics (Touch ID or Face ID) via the Mobility setting “Authentication – Biometrics” may receive a notice that “Biometric authentication is required for connection [Reason 150]”; in this case the client will not connect to the Mobility server. The only way to connect after experiencing this error is to do one of the following

• Upgrade the client to Mobility 11.72
• Change the global client setting  “Authentication – Biometrics” in the Mobility console (Configure > Client Settings) to “Do not use biometrics” and create a new VPN Profile on the client, either in the Mobility client interface or by pushing a new profile to a client using a Mobile Device Management (MDM) system.
