@beginyyuu your config looks good and the targetXPath value is correct, however, it looks like the config is being overwritten by another config as you can see in the screenshot, at the bottom, the selector is different (.sale-price/.money). Can you try moving the config as well as the reference to the script to the very bottom of the product-template.liquid or product.liquid?
Hi do you think you can assist? I would truly appreciate it. I have been at it for hours.
@MLM set your targetXPath to .product__price/.price-item--regular, and your renderToPath to .price__pricing-group
