F2-220 problems



The Plex app on this NAS keeps freezing part-way into scanning the folder containing my files of my Music library.
Does anyone have any ideas?
I've done countless reinstalls.
I'm using a MacBook (Sierra) and an iPhone.
I don't know anything about Linux (I think that is the OS in the NAS) or configuring computers.
I am using Plex as a server for my music library (or rather, I want to!).


I think it's to do with old prefs and cache on the NAS. They're old and don't correspond with the metadata of some of the files, which I've since changed.
Is this plausible?
How do I trash these on the NAS?
Can I see them in MacOS? The NAS is Linux


Restored Factory Settings. Duh.
Thanks for listening.
