M2C 2.2.3 Configurable product - special price does not display on Category page and Product page

[devhelp37]

Preconditions

1. Magento version 2.2.3.
2. Php - 7.1.16

Steps to reproduce

1. Add product as usual and set the special price for the product.
2. Add variations for size by adding under size attribute (Custom created size attribute)
3. Create the product listing.
4. Once product is created, flush all the cache and check listing. Listing is successfully created with all the variations.
5. Under Category page, cant see special price and original price together. It directly shows only special price. When we click on the product, it goes to the product page. Before clicking any attribute, it still shows only special price directly but does not show any original price. Once click any size attribute, can see both original size and also special price in product page only.Category page never displays original price at all.

Expected result

1. Special price should be shown along with Original price in category page and also product page before clicking on any attributes.

Actual result

1. Directly special price is shown everywhere on category page and also product page.

Is there any update on this @engcom-backlog-nickolas ? We are experiencing this issue on a current M2C 2.2.3 build and need it solved before launch.

Hello @PaulWMF, as configurable product price depends on price of it's children and configurable itself has no own price, it should not have it's own special price too.
So, currently there is a bug when you converting simple product with special price to configurable, Special price remains on configurable product, which leads to confusion on category page, where you see configurable special price instead of option price and on PDP, where you can see both: configurable special price and option price. Which, for instance, never happen in case you create configurable product from the beginning without conversion.
Therefore, when it will be fixed, there will be no ability to see both: special and option price on category page in vanilla magento. And it's correct behaviour.
If You want to see both prices on category page with configurable product, it would be better to implement custom solution, or try to find some 3d-party extensions which may provide such functionality.

Best regards!

@engcom-backlog-nickolas we fixed this by:

Overriding vendor/magento/module-configurable-product/view/base/templates/product/price/final_price.phtml

1. Removed the condition to check is product isn't in a list

From:

<?php if (!$block->isProductList() && $block->hasSpecialPrice()): ?>

To:

<?php if ($block->hasSpecialPrice()): ?>

2. Removed 'no-display' class from regular price span

From:

<span class="old-price sly-old-price no-display">
        <?php /* @escapeNotVerified */ echo $block->renderAmount($priceModel->getAmount(), [
            'display_label'     => __('Regular Price'),
            'price_id'          => $block->getPriceId('old-price-' . $idSuffix),
            'price_type'        => 'oldPrice',
            'include_container' => true,
            'skip_adjustments'  => true
        ]); ?>
    </span>

To:

<span class="old-price">
            <?php /* @escapeNotVerified */ echo $block->renderAmount($priceModel->getAmount(), [
                'display_label'     => __('Regular Price'),
                'price_id'          => $block->getPriceId('old-price-' . $idSuffix),
                'price_type'        => 'oldPrice',
                'include_container' => true,
                'skip_adjustments'  => true
            ]); ?>
        </span>
