I have just converted to the online version of MYOB and note that when emailing invoices and changing the email address I send it to, a popup no longer appears asking whether I want to save the new email address on the customer's card. and it doesn't save. If I go through print/email it does pop up but that route is a pain as a separate operation to email
"Prompt to update email address on card when using Enter/Edit Sales window email function"
