I lost the Zorin "DISPLAY SETTINGS" window

I updated and upgraded etc, and lost the Zorin display settings window. The one that has mirror displays etc. Now I guess I have the regular Ubuntu display settings, and it doesn't find my 2nd HDMI monitor.

How do I get back the Zorin display settings window?

Thanks

When you say updated and upgraded, we're not talking about going from Zorin 15 to Zorin 16 upgrade?

This is a fresh install of Zorin pro 16. I updated and upgraded from the terminal. Rebooted and the display settings had changed.

Try with

sudo apt install --reinstall zorin-os-desktop zorin-os-pro

All of a sudden it started working.
Thanks
