Can not sync song from iTunes to iPhone through WiFi
I used to sync songs between iTunes and iPhone through WiFi but now that pop-up menu disappear. I plug iPhone into my MAC with USB cable and disable "WiFi syncing" option the activate it again but still, the problem can not be solved. Any suggestion?
My iTunes and iPhone version are all up-to-date.
