Hello,
I am a Jira administrator for the company that I work for, and I have a customer who has not received an email. I’ve tried creating a support zip, downloading it, and looking for anything that stuck out and I was unable to find anything. I've also checked the notification helper to see if there was a configuration issue, and all seems to be well on that end also. He is a watcher on all issues that he wishes to receive notifications on. I've read in a few forums that Atlassian needed to do some backend work to resolve this issue. Can you please help me with this?
