jira.comment.collapsing.minimum.hidden setting in Jira's advanced settings doesn't work for the new issue view. It would be great if this setting works, or an alternative way is provided to achieve this.
Sometimes the agents and admins don't want to have to click to view more comments and want to have all comments being shown in the issue view.
Enable the jira.comment.collapsing.minimum.hidden setting to the new issue view.
There is no workaround.
