In my store, when I create an invoice and click on 'submit invoice',(not on 'send email') the invoice email is automatically sent to bcc email id (not to customer email) (ie; Sales Emails > Invoice > Send Invoice Email Copy To). And when I click on 'send email' then the invoice email is sent to customer and bcc(2nd time).
I want to stop the first email which is sent to bcc automatically on invoice creation
