I turned on the ON/OFF switch to the right of [Use rekordbox CloudDirectPlay], but the authentication button didn’t appear. Why not?

It may take some time for the authentication button to appear, depending on the number of tracks in your rekordbox library.

See the examples below as a rough guide.

• 1,000 tracks: about 1 minute.
• 10,000 tracks: about 5 minutes.

In addition, the authentication button may not be displayed if you are not connected to the Internet.

After connecting to the Internet, reopen Devices of TreeView.
