Before 'upgrading' from V19 to 2019.1, I would print invoices to PDF to email to customers. These files were about 10kB. The same invoice printed in 2019.1 is a whopping 454kB. I am almost embarrassed to send such a file.
I normally keep these invoice PDFs (they are part of business correspondence) but I can now see my hard drive filling rapidly. Perhaps MYOB could forego the recent subscription increase as a contribution to a new hard drive for my invoices...
