Thanks for the heads up!
CDJ 3000 1.22 Firmware update is missing from the main page (link inside)
This page https://www.pioneerdj.com/en/support/software/player/cdj-3000/#software-update , in fact there are no firmware links that can be found easily for the cdj 3000.
Users have to go here to get it: https://support.pioneerdj.com/hc/en-us/articles/900002723643-CDJ-3000-firmware
I hope that helps!
You should update the main firmware page, otherwise people won't find it.
