@kugiigi Upon install, the daemon file will be installed but not enabled/started by systemd, that inside the app does enable+start. On update, the daemon file under systemd's ExecStart will be replaced, but due to the nature of systemd, the newer version will not be executed upon next restart/reinstall daemon.

At least on my device the clipboard is still working without problem.
