offline servers shared with friend not listed

When I look at my Plex friends, for one of them (for example) it says I’ve shared 4 servers with them.

When I click on edit, to see what servers are shared, I only see the one server that is online. The other 3 are not displayed.

This is a problem because it means I can’t unshare those offline servers, which I’d like to do.

Some of those servers are not only offline, I’ve decommissioned them so they don’t exist anymore. I would really like to unshare them because it’s confusing to have non-existent servers shared.

Other servers do still exist but I can’t spin up right now, but I’d still like to edit who they are shared with.

I’d say this was a bug that should be fixed, but I’m not sure where to report bugs other than in this forum.

Thanks.

In the case of the old decommissioned server :

In Plex web go to settings > Devices > Server

There you can remove old server instances.

That worked thanks. It still seems that I should be able to more easily unshare libraries from offline servers, as well as see which libraries from offline servers would be shared if the server was online.

But my immediate issue is solved, so this because more off an enhancement request.

FYI I was decommissioning my Plex server that had been running on my Netgear ReadyNAS because the latest version supported was old (0.9.16), and was installing the latest Plex server version on an i7 NUC running Linux Mint (ubuntu based).
Things got very confused on my LAN when I restarted the old Plex server (in an attempt to unshare), even browsing directly to the i7 NUC IP address still showed the Plex server running on the NAS. (I had changed the router port forwarding for Plex from the NAS to the new NUC IP address). I’m not sure why I saw only the old server and not both servers that were running on the LAN (same subnet).

I’m not sure the above is a question (other than I’d like to understand what’s going on under the hood so it makes sense to me), since it’s not really causing an issue currently since I’m only planning on running one server (the new one) on my LAN.

There are occasions that I do want multiple plex servers running in the same LAN subnet though. I sometimes bring my laptop running plex w/ a portable media drive to someone’s house who has their own plex server, so we can watch my media from their Roku plex player.
