It’s possible to connect issue start and end dates in Swanly with date fields in Jira and keep them in sync. Once the connection with Jira fields is set, then when the field changes in Jira, it automatically updates in Swanly and vice versa. This connection is quite useful when you wish to keep using both Jira project roadmaps and Swanly, so you can keep the roadmaps in sync.
