Follow up from my other comment about invoicing. I decided to just send the existing invoice and add my comment to the email. But in the invoice dashboard I don't see any way to go back to the invoice at all. There are the listed options on what to do after the invoice is created along the left side; email, pdf or link. But all they do is open and close the panel. I will try to turn off my content blocker. I just realized that might be interfering with the web page. I'll come back and report my findings.
