In my current operation, when the user finishes paying and the order’s status is processing, the user sends a message in dispute that says, ‘I want to cancel this listing,’ to the admin.
And upon receiving the message, the admin changes the listing status to ‘cancel’ on the WordPress admin page.
At this point, I want to send an email to both the vendor and the user.
But currently, the email is only sent to the admin.
This is how it should work by default. Please try to change the status to refunded, then the customer and the vendor should receive an email notification.
Unfortunately, there’s no such feature; it would require a custom implementation. If customizations are required for your site, please try customizing it using the collection of code snippets Search · user:hivepress · GitHub and other developer resources, or consider hiring someone for custom work https://fvrr.co/32e7LvY
