Plex Media Server - Synology DSM 7 Preview - Issues

Looks like it doesn’t work on my 918+
DSM 7. 41882
Plex (downloaded the x86_64_dsm7.spk above)

I get a popup about permissions at the end. I’m following the instructions. Plex has read/write both on internal system and user. There is no “custom” option.

My plex folder is a certain shared folder.
