I'm trying to overlay a loading spinner using the Teradata / covalent UI kit, as shown in this example, however it simply won't show, no matter what I try.
I've put together a single use example here, any suggestions welcome.
It is important to load the SCSS styles for the loading spinner to appear. I recreated your example on StackBlitz and was able to have the spinner load correctly. The Angular-CLI might not be compiling your theme.scss because it is in the assets folder.
