Restore a custom product tab after a Shopify theme update

Name the exact missing feature

Identify one product, its assigned template and the tab's expected content. Was it configured in the theme editor, inserted by an app or added through a code change? Keep the previous theme as the reference and record the update version. A missing tab can be a template assignment or settings problem, not necessarily missing code.

• Capture old and new behaviour using public content only.
• Check whether the tab is absent everywhere or on one template.
• Do not publish repeated experimental themes on the live storefront.

Read the update's carryover status

Shopify theme updates create a separate draft. Editor customisations can carry over, but custom and app-generated code transfer only if compatible. Review any notice that code edits were or were not included. Compare the specific template, section or snippet with the old theme rather than copying the entire old codebase over the update.

• Inspect app blocks and theme settings on the draft.
• Recheck CSS against the updated theme's selectors.
• Preserve necessary new-theme fixes instead of blindly reverting all files.

Define a useful acceptance test

On the draft, the named product shows the expected tab and content, the tab opens with keyboard and pointer input, and the agreed mobile layout remains usable. Also check an unaffected product template and its add-to-cart path. This proves the bounded storefront change, not sales uplift or every checkout path.

• Record changed files or settings and screenshots of the agreed states.
• Name any app dependency or content that was not included.
• Keep a clear route back to the prior published theme.

Before requesting work

Send the theme names and versions, product/template affected and a redacted description of the lost feature. The account holder controls publication and grants only agreed access after scope. A missing tab does not require passwords or private customer exports in an enquiry.
