Upgrading to Synology DSM 7 without granting read/write to PlexMediaServer

4. For each share that you wish Plex Media Server to access, you need to go and set read/write permissions for the PlexMediaServer system internal user.

You decide which share the system user will have access to.
There’s no requirement to give PlexMediaServer access to all shares.
