When upgrading to Magento 2.4.2 all of the core css is missing front both the back and frontends.
Looking at the source I see no reference to such lines such as
<link rel="stylesheet" type="text/css" media="all" href="https://www.example.test/static/version1624020941/frontend/vendor/theme/en_GB/css/styles-m.css" />
Also stuff like the fav icon is not loading and reverting back to the Magento default
Anyone one got any advice
