Hello,
Would appreciate some pointers. Seems in the past few days we lost the ability to CC customers on requests in Jira SM via email. This was working perfectly before and I as an admin do not recall making any changes to the settings, yet now CC via email appears to ONLY work if the customer submits the request by email to begin with. Then 'Reply to Customer' sends them an email as expected. If however they are added as a reporter or request participant (using their email), no emails are sent (or at least none received - I don't know how to check outgoing logs for something like that).
I have it set so customers do not require a login to post or be CC-ed on issues. This is a paid cloud instance.
