Hi,
I've seen very old posts on the subjects so wanted to check if there was any update on this? Getting the burndown by count of subtasks is such a basic feature I can't believe it's not available in Jira. I've seen 3rd party plugins on the marketplace but IMO it should be a built-in Jira feature.
I've read some answers to past similar requests that completely missed the point, arguing that tracking at subtask level didn't make sense because stories are not done until all the subtasks are completed (which is true but just unrelated to the question). Please don't answer if this is your answer.
Thanks
