Systemd user service units for apps remain in failed state if lomiri-full-greeter is restarted
systemctl --user restart lomiri-full-greeter.service
is the way to restart Lomiri shell on Ubuntu Touch 20.04, and will be used by myii/ut-tweak-tool!109 (merged) for example, replacing restart unity8
used on 16.04.
The problem is currently restarting the shell leaves all previously running apps broken and you can no longer start them since their transient systemd user service units are in a failed state.
