Customers are not getting product price drop email for subsequent product price changes.

Steps to reproduce:

  1. Enable Product Alert for both Price Changes and Back in Stock in Store > Configuration > Catalog > Product Alert.

  2. Enable Display Out of Stock Products.

  3. Create a simple product (ABC) with qty = 0.

  4. Create a customer from the storefront and subscribe to the above product to get product alerts for price drops.

  5. Start the product alert for customers.

    bin/magento queue:consumers:start product_alert
  6. Drop the price for the ABC product.

  7. Trigger the product alert cron.

    php n98-magerun2.phar sys:cron:run catalog_product_alert
  8. Drop the price for the ABC product again.

  9. Trigger the product alert cron.

    php n98-magerun2.phar sys:cron:run catalog_product_alert

If you are not familiar with n98 tool, then you can run bin/magento cron:run command as usual and monitor cron_schedule table to make sure catalog_product_alert job gets success status.

Expected results:

The second price drop email is sent.

Actual results:

The second price drop email is not sent.
