Oke.

I don't get the logic of the folders:
In one library (on Google Drive) there are no folders at all,
In another: some files are in folders, some are not.
This differende might originate in the settings: at least one library was made before I switched to 'no subfolders'.
I switched because you made that the default setting in the app.

All members (except the voice-managers) only have reading rights in the Google Drive.
None of them adds files locally. They just sync down.

Different libraries are situated in different Google Drive folders.
