Often when we receive a message from an invoice, it alerts us of that new message via our email. However, it will send a message in a thread of other invoice messages. This needs fixed as lots of messages are missed because a new message will come in and add it to the thread that showed other messages, which make the others get lost and we have no idea a customer wrote back. We have to many orders to have to go to the invoice and check the message section of every invoice throughout the day to ensure they don't get missed in a sea of message threads.
