This works well for me locally!

The only issue that I found is that https://pr-2671--spectrum-css.netlify.app/preview doesn't seem to be working, and clicking on "Component Preview" leads me to a Chromatic url:

I know we had that issue before, did we find what was causing it then?

That's correct and expected behavior. If Chromatic builds, we use that link for preview instead of re-building locally. If the VRT step is skipped, it builds it locally so you get a /preview result.
