Cloud version. I'm an admin.
I had someone @ mention me in a comment on an open ticket that we all have access to. The email isn't being sent. Other users are reporting this issue so I ran tests with my own account.
The Jira Notification Helper doesn't have the option for the @ mention feature, which seems odd.
I see where others have reported this issue historically but no real solution or maybe Jira just fixed something and made it work again. Any suggestions?
