Djay 2 for iPhone wont re-sync itunes song information.
For example, 6 months ago I had 100 songs with only 20 having BPM. Now I have 200 songs and every song has a BPM in iTunes. It will read the 200 songs, but still only display BPM for the first 20, the other 180 have no BPM. I read my itunes playlists through Djay 2. I have tried deleting every song from phone and re-importing, no luck. I cant find a sync or update function anywhere in DjAy 2.
So after entering the tapping the BMP for my songs and adding to itunes, (closer to 1000 songs) I was very disappointed when djaying and all my data was not there.
