# Other Common Issues

> Troubleshoot metafield values, missing ratings, icon upload failures, theme changes, and Online Store 2.0 requirements.

## **Metafield values do not show**

Confirm you connected a **product** metafield, not a metafield that only exists on another Shopify resource. Verify the namespace and key, then confirm the product has a real value stored.

## **Ratings are missing**

Ratings require data in Shopify that the **Rating** attribute can read. If you use a review app, confirm it writes ratings into **product** metafields your setup expects. No review app means there may be no rating to display.

## **Icon upload fails**

Attribute icons must be **500 KB** or smaller and should be a normal image file. Reduce image size or re-export the file, then try again.

## **I changed themes and tables disappeared**

Each theme has its own app embed and block placement. Re-enable **Iconic Product Comparison** under **App embeds** and re-add **Specification table** and **Comparison table** blocks on the product templates in the new theme.

## **Online Store 2.0 requirement**

This app relies on **Online Store 2.0** features such as app blocks. Vintage themes or sections that cannot host app blocks will not show these app blocks on the storefront.
