When I am using the Windows app for the RS130(b) but I cannot see the my NAS drive content in the “Album” view. My music is stored on a Synology DS223 NAS drive.
I don’t have any problems seeing the content using the Android app nor when I access through the unit itself.
We also connected the RoseConnect Windows app to the Rose device just like you, and the NAS music was visible in the album without any problem.
So after checking the photos you sent, I confirmed that your RoseConnect Windows app is not the latest version.
Please go to the link below and install the new RoseConnect Windows app.
