WAIT: 320 media query does not show up in google dev tools

can anyone help with this… I create a mobile custom break point for 320px. I save, refresh canvas, refresh browser, update header template, flush WP site catch, delete temp files etc and but 320 media query does not show up in google dev tools.

Also, make sure to regenerate breakpoint CSS files:
