You mentioned here that all Plex clients have gotten an update.

Even the officially supported Snap got this update.

But the officially supported Flatpak hasn’t gotten an update in 9 months on version 1.112.0 and is using EOL run time.

Can you please update the officially support Flatpak to that version as well and also update the runtime to a support one when.
There have been PR’s for it been no one has taken any action on this.

Also see this topic which was created a year ago where this was asked and no Plex employee responded but one who said he contacted engineering and he couldn’t do more.
