Yes, my template has a section containing a liquid, let’s call it custom.liquid. After updating my Dawn theme, the liquid/section is removed from the template.
Topic summary
Issue: After updating Shopify’s Dawn theme, a template’s Custom Liquid section (custom HTML/Liquid added as a section) disappears from the live template. The section file still exists in the code, but it’s no longer referenced in the template, requiring manual re‑addition each update.
Clarifications: Other participants note that theme updates install a fresh copy that does not include prior customizations in templates. This suggests the behavior is expected rather than a bug.
Follow‑up: Questions were raised about whether settings were hidden or tied to specific HTML, but the reporter confirmed the section is removed from the template after updating.
Official guidance: A staff response links documentation stating manual code changes are supported, but files/settings in the templates folder are not copied over during updates. If a custom templates folder was created, it won’t be migrated; manual handling is required.
Status/Actions: No automatic fix provided. Recommended to track and reapply template references after updates or adjust customization strategy to minimize template-level changes. Discussion effectively resolved as expected behavior; no automation/workaround detailed.
