I've tried everything I can think of and advice from other similar Q&A, but at least 2 people don't receive emails when directly mentioned in a comment on an issue via card. I created an automation to automatically add everyone to every newly created card. The automation works, but they don't get email via direct mention. I added the jira-software-users group to the issue comment event, and that is recognized, but that didn't fix it. I looked up both users via notification helper, it says they should get them, but they don't. Both users have verified that their personal notification preferences are all checked as "on", but that didn't change anything. We are using jira cloud.
Can you help?
