basically i go through each step of syncing my music to my ipad4 but nothing happens. i go into itunes, click on the device, then on music and pick either sync entire music library or sync selected artists, playlists, etc. options. as soon as i do this, the music appears in the bottom bar which shows the ipad's capacity etc, i click on apply and the moment i do so the music disappears. i've tried restoring, disconnecting and connecting again, i've used different cables NOTHING HELPS. if here is anybody who is able to help me solve this issue, i'll be very grateful.
