Plex media server not starting after latest update on Synology

ESo I’ve updated to the 64bit version and all of my metadata loaded, so everything looked ok, but…

PLEX doesn’t find any new files when I try to add them, even if I force a library scan. Is anyone else having this problem??

I added files to several libraries after all of these issues seemed resolved, and PLEX isn’t finding any of them.

THEN I realized that PLEX loaded all of the metadata for my libraries, but ALL of the files are unavailable. What am I missing? I can’t play anything.

UPDATE- apparently This new update DSM update required me to give PLEX permissions for Read/Write, so now it’s working.
