Bug en XDJ-RX

Sorry, I'm not sure exactly what the problem is - you say "y se pega" but what exactly isn't working? Can you tell me what you're doing step-by-step?

Okay:
Uso la XDJ-RX con el iPhone en rekordbox, cuando hago un hot cue, se hace un bug, y tengo que reiniciarla, desconectándola completamente.
Es solo con la aplicación del iPhone, con pendrive sirve perfectamente, pero con el iPhone si.

Por los audífonos suena como si estuviese haciendo un 1/6, se traba

Which version of the app which version of iOS are you using? The current version of the app is 2.1.1.0.

Yes I'm using 2.1.1.0

Which version of iOS on which model iPhone?

I have 10.1.1 and 6s

Was the song imported on the phone or from rekordbox on your computer?

Yes I import my music from my computer to the iphone and when I do a hot cue stops working

And that's when the phone is connected via USB and you call the hot cue from the XDJ-RX, correct?

Yes
