I’ve started rekordbox CloudDirectPlay, however sometimes tracks are not appearing on the browse screen and I can’t seem to load tracks. Why is this?

There are 3 possible causes to this issue, as follows:

1. Cloud Sync is incomplete
   If the Cloud Library Sync between rekordbox and the library in the cloud hasn't finished, the track won't be displayed on the browse screen. Wait for the sync to finish, then the track should display.
2. The track hasn't been uploaded to Dropbox
   Only tracks that you've uploaded to Dropbox will be displayed on the browse screen.
   If the upload isn't complete, the track can't be loaded.
   Upload the tracks you want to use to Dropbox beforehand, then use them once the upload is complete.
   You can upload with rekordbox.
3. Impact of Dropbox maintenance or failure
   When Dropbox is undergoing maintenance or experiencing problems, tracks can't be loaded. Try again when Dropbox is back online.
   You can check the status of these issues on the Dropbox website.
