Why is my size chart not showing on the storefront?

First confirm that the app block is saved on the correct product template, then check whether the product matches a live chart.

Check these items in order:
  1. Confirm the block is present. Open the Shopify theme editor on the product template and confirm Apps → Size chart has been added and the theme was saved.
  2. Check the chart match. In the chart’s Where it shows section, confirm that the product is assigned directly, belongs to an assigned collection, matches an enabled Pro rule, or is covered by Everything else.
  3. Check the Free selection. On Free, only the three selected charts are live. Additional charts are paused, not deleted.
  4. Confirm the chart save completed. A successful save writes to your store immediately. If the app reported a failed save, no change was published; correct the issue and save again.
  5. Check the correct template. A store can use different product templates. Make sure the app block is on the template used by the product you are testing.
  6. Use Simulator on Pro. Select the product to see which matching levels were checked and which chart, if any, won.
The app cannot inspect your theme, so it cannot automatically detect a missing block. If nothing matches the product, rendering nothing is the intended behavior.
