New User - How to make djay 2 find music on android tablet

Hi folks. I am a brand new user of DJAY 2 on a Samsung Galazy Tab S2 android tablet. I have a USB thumbdrive attached to the tablet using an OTG cable. My file explorer programs can all see the drive but when I open DJAY 2 it doesn’t list any of the songs on the drive.

How do I tell DJAY 2 where my music is? Or how does the program on Android work since there’s no iTunes?

Did you ever receive an answer to your question? I am having the same problem
