After upgrading to sonicTransporter 2.6 new files copied manually to the storage are no longer detected in real time. (I have not tested ripping of CDs)
This worked fine as recent as the day before on the same Roon version.
The files are downloaded from HDTracks and copied to the Storage with the same structure with a parent directory for the artist and each album in a folder under this.
The albums and/or tracks do show up in Roon when going to Settings > Storage and selecting Force Rescan from the Music Folder drop down menu.
The albums and/or tracks also show up after a reboot of the sonicTransporter.
