Changing Date/Time Widget on Google Nest Display

Hey guys,

We have a normal Google Nest and the Date/Time widget is too small for our parents to read on the dashboard we have created, if we change the font in the YAML to 100px (really large) as seen in the photo below, it does not seem to effect the casted dashboard.
