Is there any update to this issue,   The last known Quickbooks comment was in January and it is now April and I am still experiencing undeliverable invoices.   I have started looking at competitive software for this reason alone.  I have used Quickbooks in the past and this has never been an issue.   It would be great if the company advised us and announced the progress of the issue.   I have reached out to support twice and my info just seems to get added to a long list of dissatisfied clients.  Please advise
