When anyone adds comments to an open ticket within the Support portal, it's expected that everyone that's on the "Email CC List" will receive a copy/email notification of it so that they are kept in the loop. This is not happening. Is this expected behavior or have we identified a bug? If the former, then there's no use in adding comments to the ticket via the portal/community - and instead, we should just use the existing email notifications to provide additional comments/feedback for the ticket.
I'm sorry about the delay; I just spotted your question. Let me check with our developers on this and get back to you next week.
