I am trying to use the Release Burndown chart in a Confluence page, but no matter what I edit about the issues I'm trying to see, I always get the result "This chart cannot be displayed" because "There are no estimated issues in this version".
I've tagged the epics with a Release Version. Pretty sure I tagged the actual child issues with the Release Version as well.
For estimate, I tried various fields (some may be custom fields) with "estimate" and "story points" in the names. Idk what I'm missing here...
