Ok, so here’s what I found.

On linux (in my case Ubuntu) you don’t “uninstall” the old version; you install the old version ontop of the new version. When you do, this overwrites the existing (newer) version with the older version but keeps all of your library / settings / etc.

It took some piecing together but I want able to download the old version from Plex (it’s available but there’s no URL for it; it was a combination of using this list of plex releases here combined with this post here on downloading old versions:

(Mirror of comments incase deleted)

Basic process is to go to Plex.TV/downloads and right click on the link to download the current version and copy the link address. Paste it into a text editor. For example the current version download for Windows is:
https://downloads.plex.tv/plex-media-server/1.9.3.4290-9798172d4/Plex-Media-Server-1.9.3.4290-9798172d4.exe
If you are using a different OS the method is the same you would just have a different URL. For OSX the URL would be something like:
https://downloads.plex.tv/plex-media-server/1.9.3.4290-9798172d4/PlexMediaServer-1.9.3.4290-9798172d4-OSX.zip
You then need to know the prior version number, the full version information not just 1.6.1. For 1.6.1 the version info was: 1.6.1.3722-4955e31cf
We then replace the current version info (1.9.3.4290-9798172d4) with the prior version (1.6.1.3722-4955e31cf) we want to download so the new link for version 1.6.1 becomes:
https://downloads.plex.tv/plex-media-server/1.6.1.3722-4955e31cf/Plex-Media-Server-1.6.1.3722-4955e31cf.exe
Paste the new link into your web browser and the download should start.

I then used wget to download the file to a directory on my server. Once there, I ran it using “sudo dpkg -i packagename.deb” and it was done.

Just remember if you’re using a plex update script to disable it.

At this point I’m on 1.13.9.5456 and am waiting to see what happens with the recording. Will report back.
