dynuiuc is installed and enabled but will only actually update when the service is launched or restarted. When checking service status the folowing message appears:

/lib/systemd/system/dynuiuc.service:5: PIDFile= references path below legacy directory /var/run/, updating /var/run/dynuiuc.pid → /run/dynuiuc.pid; please update the unit file accordingly.

Can anyone recommend a fix for this?

I simply changed /lib/systemd/system/dynuiuc.service as suggested in the message and it works :)
