XDJ-RX RekordBox 4.1 Pro DJlink not work!!!

Hello, I am in possession of a XDJ-RX firmware just updated to version 2.10
released from you and use rekordbox 4 for at least three months, until the
4.0.8 version I was able to use the DJ Link function via the ethernet cable
and I could read songs from the playlist directly from my PC.
Updating to version 4.1 I have unfortunately found that this function is no
longer compatible, can I know why you have removed this device from the
list of compatible? What good is having Rekordbox button on the console if
I can not use it? There seems to be a normal thing to update the software
and eliminate a console worth € 1,500? I hope you solve this serious
lack !!!!! I'm seriously thinking about moving to the competition ....
I await your prompt and convincing response. Thank you.
