Hi,
The issue you're facing appears to be related to the PHP mail function, which can sometimes result in delays or failures when sending emails.
To resolve this, we strongly recommend switching to an SMTP service for sending emails, as it is faster and more reliable. This change will help ensure better email delivery and reduce issues related to payment notifications.
Additionally, to prevent timeouts during transactions, We suggest increasing the Execution time from 120 seconds to 300 seconds.
