I have a colleague who states this functionality appeared for about a week last week, then disappeared.
On a JIRA board, when an issue's Due Date passes, the Due Date is shown on the card details and is highlighted red with red text. No additional configuration appears to be necessary.
I found this Suggestion which indicates that this is functionality, but currently only on Team-Managed projects:
https://jira.atlassian.com/browse/JSWCLOUD-27109
The projects my colleague referenced are both Company-Managed projects. So it seems like perhaps Atlassian was testing something or accidentally enabled this functionality. Does anyone know anything about this becoming available for Company-Managed projects?
