I have placed a successful order in Commerce and it's settings have an email setup to send an email to the customer and use the example special/receipt email.
But the receipt email is not sent once the order is placed.
If we login to the admin and go to the order page, selecting Send Email and choosing the customer receipt then it does send it OK.
So the receipt email is all setup OK and sends using the function in the order screen, its just not sending after the order is placed.
There is no commerce.log in storage. web.log doesn't have any logs related to commerce or the order. There is nothing in the Queue related to this (only loads of failed "Updating search indexes" and "Generating products sitemap" which is a whole other issue).
Does anyone know what it could be or how I could even go about debugging this when email works and I can't find any logs about its not sending?
