A currency can stay in use by many parts of your store: product prices, variant prices, shipping rates, product feeds, markets, country currency mappings, checkout settings, checkout fees, cash-on-delivery rules, discounts, duties, and storefront configuration. Tringify blocks removal until those references are moved or removed.
- Open Settings > Currencies and try to disable or remove the currency.
- Review the dependency details returned by the platform.
- Open the listed sections and move the currency references to another currency.
- Return to Currencies and retry the disable or remove action.
