If you want to sync your automation tracks with other users, you need to turn the Personal Sync setting off.
If you have already recorded automation tracks with the Personal Sync setting on and you now want to share those automation tracks, you would need to turn the Personal Sync setting on, view a song, long-press the automation button and select Copy. Then turn the Personal Sync setting off, view the song again, long-press the automation button and select Paste. Then repeat for each song that has a personal automation track.
