The last fully working plex update (where my pictures are not lost) is PlexMediaServer-1.15.4.993-bb4a2cb6c-x86_64
I know that this might be a permission issue, however I’m not able to fix it under Synology NAS level. I’m familiar with the following forum: Plex Media Server security changes for Synology users
or with Q18 as suggested by Plex support. I’d very much appreciate your help here. I can send to you my plex log files if needed, or anything that would help.
