I have 3 invoices that are bouncing back undeliverable. I have the correct email address for each customer that I have sent invoices to multiple times in the past. I see that this problem has not been resolved since 2021. This is unacceptable customer service. We are loyal QuickBooks customers. You expect timely payments for your service, and we expect that from our customers as well, but that can't happen when we are unable to email invoices. You offer the same scripted answers for every question in Quickbooks community. It's always a waste of time.
