I’m not able to see due dates for any issues. Created date is visible.
The due date is imported both as measure (Issues due, grouped on Time dimension based on the due date) and property. Please see more details in the Jira core measures import: https://docs.eazybi.com/eazybijira/data-import/jira-issues-import/jira-core-measures-and-dimensions.
Please let me know if you have further questions regarding this!
