Need to disable @Mentions in Comments and/or edit .vm templates that construct email notification. Upgraded to Jira Core Server 8.20.17 today, from 7.13.8, and [still] have auto-notifications being sent from @Mentions in any Comments field. I researched some and this looks related to a plug-in, but don't see that Confluence Mentions Plug-in on my system. I've successfully edited various email templates, for HTML and Text, to remove the calling-code for some fields, so that sensitive Issue Title and Issue Description content is not displayed in email subjects or body. Still need to edit some more of the email templates, though, and the Comments, and the @mention in the Comments is one of the notifications that I need to either edit or disable. Please advise. Thanks!
