incase it catches anyone else out, some google fonts I was using broken when I upgraded this, I’m assuming because the new version has some stricter rules around how to use imports with postcss.
Relevant tailwind docs:
What fixed it for me was I put my font imports into a new css file and imported that into App.tsx

One other note is that the fonts worked fine with yarn rw dev, had to use yarn rw build && yarn rw serve to replicate broken fonts and then test they would work okay in prod after fix.
