Hello,
While watching the tutorial for Advanced Roadmaps, the timeline / plan was aggregated on a Sprint Level, along with the dates. See Image 1. But when trying it out, it is not possible to show the Sprints in the plan, only as a column / field. See Image 2.
I am using Jira Cloud. Maybe this is not available for cloud, only for server?

Thank you in advance,
