I am not sure if this is a bug or configuration problem.
I have a store current in testing, the store only accept Check/Money Order at the moment. When I ordered a product as a guest using the check/money order payment method, I received an email saying:
“Once your package ships we will send an email with a link to track your order.”
But if I go to the admin control panel and set the order already being shipped and invoiced, it doesn’t send an email automatically to the customers. Did I do some wrong here? because without the email, customer who is a guest is impossible to track their order.
P.S. I should also say if I click submit invoice in the admin control panel, it doesn’t seems send a copy to the customer too.
