I could not see the update on the windows insider program. I uninstalled it and could not then reinstall the new version, saying it was already installed. I rebooted the phone and then was able to install the new windows insider program, I enrolled in fast ring, and after a restart, unenrolled from the app, and it then let me see the firmware upgrade, which is installing now. A few steps, but far batter than a phone reset! Glad Microsoft figured out a way around the firmware update issue for insiders!
