Upgrading to the Windows 10 Fall 2018 release requires that you also upgrade to the Mobility v11.43 client. Microsoft is releasing their Fall update to Windows 10 (v1809). The Mobility v11.43 client for Windows fixes compatibility issues with the Windows 10 network location awareness (NLA) feature in Windows 10 v1809. Without the updated Mobility client, any application that uses this feature will malfunction, including the Edge browser and many Windows system apps. Windows 10 devices running Microsoft’s fall release must install Mobility v11.43 to avoid these issues. See Known and Resolved Issues for details.
