CSS not loading in Sprockets on 2.0.0

[jonathandean]

I have an app with madmin working without issue until 2.0.0 and after upgrading I see no styles.

My app uses sprockets and importmaps. I have also tried to run the install generator again and also generate views.

The console shows that it can't fetch the newly split CSS files

Does 2.0.0 require propshaft and cssbundling-rails?
