Hi
I have just upgraded to the latest firmware on my XDJ-RX3 and noticed multiple issues.
1) For some reason after a few minutes use certain songs begin to display the "Key" in place of the "Artist" icon, when you scroll past these it changes the title of the column from Artist to Key. Eject the USB and its back to normal for a few minutes.

2) Space & Noise Sound Colour FX are unselectable. Do not work in USB or Software control mode

3) Vinyl Speed adjust setting no longer saved. As you can see in the video if you turn it on in settings it doesn't save when you power down the controller. Very annoying as I don't want to have to remember to enable this everytime.

Several different USBs tried plus Export & Performance Mode on Rekordbox all returning the same results!
