From Cloud 1.4.23 version and Server/DC 4.0.0 version TeamBoard Proscheduler supports mapping Start date and End date to Jira fields. Each project in Jira has different Screen Scheme with different Fields therefore you need to configure the field mapping at project scope.

Please keep in mind that when mapping date fields to Jira fields the app follows Jira’s spec and some advanced feature such as scheduling task multiple times or planning 1 task for many users are not supported.
You can configure from Project Board Setting or from App settings

From teamboard in project click the setting cog on the right to got to Board Settings → Fields Setti
Turn on the option “Map dates with Jira fields” and select the Jira fields you want to map to Start date and End date.
Depend on your project Screen Scheme the issue types in project may not have the fields you picked, this list shows a current statuses. The issue types which don’t have the fields won’t work properly, you should add the fields to the Screen of those issue types
