Hello,
When I'm adding a new asset, it's asking me to select the format now from a dropdown menu:
.css
.css.liquid
.scss
.scss.liquid
.js
.js.liquid

which one should I select? I tried with scss.liquid and it gives errors:

This file contains the following errors:
Line 8 — Liquid syntax error: Unknown tag 'schema'

can you please help? 

many thanks,
