1. Are you using new styles that are visible or are you inspecting the selected elements?  
Maybe these styles are applied indeed but simply not visible.
2. I encountered an issue with similar symptoms, it could be a [CORS issue with browser sync](https://discourse.roots.io/t/sage-9-browsersync-not-loading-any-css-at-all-on-yarn-run-start/11332/26?u=strarsis).  
Edit: I notice that you added something related to your browser sync config, the `cors` option mentioned in the discussion I linked to above may do more than adding this particular header.
