Sending an invoice per email goes to primary address, not to billing
I have found this post on StackExchange: https://civicrm.stackexchange.com/questions/9094/sending-an-invoice-per-email-goes-to-primary-address-not-to-billing
I tested on CiviCRM 5.68.1 and it seems that CiviCRM still only sends the invoice to the primary address.
What do you think about a setting 'send invoice email to Billing if it exists, otherwise send it to Primary'? The setting could be optional so that nothing changes for users who want to keep it as it is. Or is there any knowing extension already that I could not find? Thanks in advance!
