Platform Notice: Cloud - This article applies to Atlassian products on the cloud platform.
Summary
Changes done to the Due date field are not reflected on the Timeline.
Diagnosis
Verify if there is a custom field called "Due Date" under the custom field section of the site.
Navigate to Settings -> Issues
Under FIELDS, select Custom fields.
Verify if this custom field is added to the Issue type screens of the Project.
Cause
If there is a custom field created with the same name "Due date" ( which is actually a system field present by default in Jira) then any changes made to this custom field will not get reflected onto the Roadmaps of Jira. More details about Start date and Due date schedule can be found on the page Epics in Roadmap
Solution
Make use of the system field "Due date" in Basic Roadmap, for scheduling, by adding it to the appropriate screens of the project. Don't create a custom field with the same name as the system field. Rename 'Due Date' custom field to a different name to avoid any confusion.
