If you recently upgraded your online store to the latest version of Magento, specifically Magento 2.3.3, you might encounter a Paypal issue during Magento 2.3.3 checkout or when placing orders. While the upgraded store appears to function properly when it comes to adding products to the cart, going through the checkout process, and placing orders, there seems to be a problem with the order confirmation emails not being sent.
This issue can be particularly frustrating as order confirmation emails are essential for both merchants and customers to ensure successful order processing and communication. Resolving this specific PayPal issue in the Magento 2.3.3 checkout and order placement requires a thorough investigation. It is advisable to check the configuration settings related to email notifications, review any changes made during the upgrade process, and ensure that the appropriate email templates are properly set up within Magento's backend.
Troubleshooting steps may also involve examining the Magento and PayPal integration, verifying API credentials, and considering any recent patches or updates provided by Magento to address email notification issues.
