I just installed kdeconnect on Fedora 42 Workstation. Everything works except that when I click the “Plugin Settings” for a connected device, nothing happens.
$ kdeconnect-cli --version
kdeconnect-cli 25.08.2
Sounds similar to the bug report here: https://bugs.kde.org/show_bug.cgi?id=504540
In kdeconnect 24.x kdeconnect-settings is a separate app, which does work.
