If "Enable On-air status" mode is enabled the channel fader must also be down before the track is updated.
The "Enable On-air status" switch will only be available if you have a Nexus 2 mixer connected.
Now Playing will update when the CDJs change master tempo. Your CDJs will automatically change master tempo.
You can also press the master tempo button on your CDJ if you want to update Now Playing manually.
