How to change currency on product page

Hi,

This is done within WooCommerce's settings.

https://docs.woocommerce.com/document/shop-currency/#:~:text=To%20change%20your%20shop%20currency,or%20right%20of%20the%20price.

Note: As WooCommerce is a third party plugin outside of GeneratePress. The level of assistance we can provide is limited if in case you come across any issue as this is out of our scope of support. It is best to refer to their documentation/knowledgebase or ask their support regarding their plugin.
