Published Figma Sites no longer support custom non-Google fonts?

Hi ​@Ashley Shugart, thanks for reaching out! 

I understand how this must be disrupting your workflow. To clarify, published Figma Sites still do support custom fonts. One thing that may be happening here is browsers need a web font file served with your site. This means any custom font has to be uploaded as .woff or .woff2 under Site settings → Fonts before publishing. Another thing worth knowing: if a font file gets removed while text layers are still using it, the published CSS keeps pointing at the missing file and the browser falls back to default sans-serif, which lines up with what you're seeing after a few delete/re-upload rounds. A few questions, so we can help: 

• In Site settings → Fonts, are the .woff/.woff2 files still listed after your most recent publish?
• Have you hit Publish → Update since the last upload? (Uploading alone doesn't push it live.)
• Any specific weights or styles affected, or all of them?

Here's the full walkthrough in the meantime: Add a custom font to your site. If everything above checks out, and it's still falling back, that points to something on our end. Let me know, and I can help connect you with our support team to investigate further.
