MusicBee sync question - duplicate checking

[splatt]

I've been trying to sync MusicBee to my phone via USB, and it seems that  it doesn't check to make sure that it's not creating duplicates - it just sends everything right on over regardless of if MusicBee has previously synced the song or not. This when I just barely synced the device 5 minutes ago and haven't even disconnected the device. Is that how it's supposed to work?

I don't experience that issue.

What version are you using?

3.3.7165 Store

You might want to try the portable version.

I might try that. I discovered I was tapping "PTP" instead of "File transfer" on my phone. switched that and it seemed to fix itself
But there is a second issue that keeps coming up as well - It keeps telling me that the storage folder no longer exists and may need to be changed in the device sync preferences.
