Timeline not grouping child items to Epics

[Chris Marshall]

Timeline view is no longer grouping child items under Epics. Also within my space there isnt a toggle to group items together. Any ideas how to reconfigure board?

Hi @Chris Marshall

Thanks for the question.

Is this happening in a single project or across all projects?

I just checked in my Jira Cloud instance, and the Timeline is still grouping child issues under their Epics as expected. If it were working previously and suddenly stopped, I'd check whether any Timeline filters are applied and whether the issue hierarchy (Epic → Story/Task) is intact.
