Multiple e-mail address for one invoice

I used to be able to send an invoice and statement to multiple e-mail address, but since the spring 2016 update, I am unable to. 

I had a mailing list set up in my e-mail program for the multiple e-mail address with a name, ie Sobeys. and in the Sobeys mailing list, were the 3 people that needed to receive the invoices.  In Sage I had the e-mail address as the mailing list title ie Sobeys.  It always worked, for years.  Now, since the update, Sage doesn't like the mailing list title, says it is an invalid email address.   

So then I added the three email address into the Sage email with a comma separating each address.  Works for invoices, but not for statements.   Statements only want one e-mail address. 

Is there going to be an update that corrects it back to the way it was, or have another way of doing it.  Or am I missing something
