I've modified the invoice starter solution to create a custom app for my client.
However, upon sending an invoice by email (using Outlook 2016 - Windows), something weird happens.
First, a blank email is created with none of the content (or attachment) from the script.
However, if I then close that down, a correct new email is created that I can send as it's supposed to, complete with addresses, placeholder text and attachment. But it's obviously a pain to have to delete the spurious blank one first.
Anybody any ideas what might be going on?
