I still have a bung portable MusicBee post-remap - and I have a hunch the remap is the root for the troubles that after the remap, monitored folders / rescan does not work as intended anymore.
I have the case where I had this in file structure (pre-remap):
/labelA/
/releaseB/
/releaseC/
/releaseD/
And upon moving data to the new location (which I later remapped MusicBee to), I also added new albums to the above, so it looked like:
/labelA/
/releaseB/
/releaseC/
/releaseD/
/releaseE/
/releaseF/
And within the new location, after having the old library paths in MB remapped (so /releaseB/ through /releaseD/ were working again as intended), a re-scan of the monoitotred folders, which the above is part of, simply does not see the additional
/releaseE/
/releaseF/
folders within the monitored folders no matter what I do.
If anyone / Steven wants me to test / check something with the MB portable setup exhibiting the above behaviour, sing out, otherwise I will re-install MusicBee from scratch tonight or tomorrow as well to fix the issue & set up my library from scratch again.
Cheers.
