Hi @damien,
Windows is indeed working… 
I successfully transfer a playlist from Traktor to Serato and everything (Grid, Cues, Loops, Metadata) has been transferred. Only “problem” i found till now is that the “Date Added” column on Serato wasn’t transferred from Traktor (Import Date Column), but it shows 8/2/2020, i don’t know if that’s on purpose or if it’s not possible to transfer that data from Traktor but i would be useful to me to have the original import data from Traktor!
Keep up the good work and have a nice weekend! 
Problem solved by the way… 
Also it’s time to change the windows beta coming soon thing on the main site… 
UPDATE: Track color has not been transferred, I’ll create a new topic for this!
