Not getting notifications in Slack intermittently when someone tags on Jira Issues with @mention notification
Platform Notice: Cloud - This article applies to Atlassian products on the cloud platform.
Summary
The user is not receiving some @mention notifications from Jira to Slack
Environment
Jira Cloud
Diagnosis
Verify if 'Someone mentions you' is checked for personal notifications for the affected user
Cause
Check whether the user is not getting the slack notifications for the issues with private comments.
It is to be noted that if there is a private comment with certain visibility restrictions, it is an expected behaviour, wherein we don't send Slack notifications in such cases.
Solution
For issues, where all the comments are private and visibility is restricted, no slack notifications will be triggered. Consider changing the visibility of the comments if it's necessary to trigger a slack notification.
