Hello
I have a big problem with the new Plex Firmware for Drobo 5N. I was on 1.16.xx but used the system for months. Now I updated my Drobo to 1.18.7.xxxx but it doesn’t show my local media/movies/etc.
I have the same issue on the Synology DS1515+
My 3. Plex Server on a macmini works normal? What is going wrong? Has Plex kickoff this 4-5 years old NAS from their supported list
