1.6 Dropbox over 2 computers

Hiya, I have 2 computers. A Mac Pro, and a MBP. I have 1.6 on both.

I added some songs to my dropbox library on my Mac Pro - Ensured DB had updated and uploaded to the cloud. Shouldn’t the same songs show on my MBP?

I checked that everything had been updated on both sides. Is there an update button?
