I have a Jira Advanced Roadmap where the colour is set based on the health of the issues. (Health is a custom field I believe). I can update the health of initiatives/capabilities/epics/tasks, but there is no option to update health for sub-tasks. This means some of my roadmap is greyed out. Is it a Jira restriction that health does not apply to sub-tasks, or is this maybe a restriction in how my admin has configured this custom field? TY
