ok, here’s the fix:
ON YOUR PLAYER , GO TO YOUR SETTING IN YOUR TOOL MENU THEN SELECT YOU “PROFILE” there is a QR code - scan it and it takes you to the log in page of your account
LOG IN WITH EACH DEVICE
THE STEMS APPEARED !!!
I also disconnected my WIFI and connected the mixer to the Ethernet .
well this is fun!!!
updated
Any chance you’ve tried to read page 44 of the SC6000 manual?
A new topic isn’t needed, so unapproved.
no sound after player were connected. shut down,re-started and went in to mixer utility and re-freshed the IP address..
works like it should now…
my only issue is the stems dont sound great … yet. but im sure that improvements will come in future updates !!!
DDJ need to make this process easier or at the very lest, put a tutorial up for us to use.
I hope this helps at least one other person .
peace , love and music to all !!!
no, who reads their manual 
i do. that’s why it exists.
Randomly, those who prefer to avoid being seen as idiots or lazy by coming to ask questions on groups or forums, the answers to which are found in the manual in 95% of cases.
I read manuals before buying stuff, so I know all functionalities and limitations 
I do the same thing.
