Hi,
A few things you need to read because Plex on DSM 7 is radically different than DSM 6 which means a lot of the existing threads and how-to’s are outdated.
On DSM 7, username PlexMediaServer must be granted permission to read the shared folder(s).
You might want to read a bit of this to familiarize yourself with setting things up
(there is a special FAQ at the bottom of this post for first time setup)
I do recommend you upgrade from the Package Center BETA app to one you download from https://plex.tv/downloads as soon as possible.
It was created for when DSM 7 was beta. It does have a lot of problems now that DSM 7 is final release.
