Reply to Traktor DJ Metasync and S2 integration

Hello,

I'm trying to set up traktor DJ on my phone so that I can prep tracks when I'm on the move. I've gone through the set up guide on the native instruments website. It says select Preferences > Dropbox. However I don't have the dropbox option so I can't even turn it on. Has anyone else had this issue? Seems like a weird one, probably just me being a ReeeeeeeTard.

Also is there anyway I can use TDJ in my sets, the main reason I ask is that I like the effects lay out more then turning the nobs on my S2. If there isn't anything on TDJ does anyone know any different apps that could work?

Thanks,
