Invoice not sent to customer.
I send an invoice every week to the same customer. Invoices are duplicated each time and the customers email address is automatically filled. I got a message in QBO saying "We can't reach this customer. Please verify the email address with your customer or use a different email.". The email address is correct but the "Send" button is greyed out. I deleted all my cookie, etc. but that didn't help. I tried using the QB app instead and it appears that the invoice went through (I will check with my customer). Why is QBO blocking invoice delivery to an email address that is active? This is not on the customers end because the email is never sent from QBO. I pay for QBO for the convenience of delivering invoices. I do not want to print them to a pdf and manually email.
