We were just made aware of an issue with our site where the Processing Order emails are not being automatically sent to customers. Other order status notifications are being sent as normal (for example the confirmation sent to us once a web order is placed).
I installed the Post SMTP plugin a few days ago in order to track the status of emails being sent from the site, and all seem to be functioning as normal, with the exception of the Processing Order messages (these aren’t being automatically triggered at checkout, but can be sent manually after the fact - I attached an annotated screencap of the log demonstrating this).
After searching around online quite a bit and coming up empty handed on a working solution I’m completely stuck at this point. Any help would be appreciated!
