Djay 2 for iPhone wont re-sync itunes song information.

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.

Please note that there are BPM values given by iTunes from the very first. These are only approximate.
After analyzing track in djay 2, the correct BPM is shown in djay. As djay can only play from iTunes, it is not able to make changes within iTunes.
That is why it cannot “sync” BPM data to iTunes…
