If an additional Jira project needs to be added to your sync, consider the sync mode you originally selected.
Was the JIRA source created as a one-time sync? If so, we suggest creating a new source with the missing project.
Was the JIRA source created as an archive or auto-sync? If so, please contact Onna Support, and we will update the list of JIRA projects selected to sync.
This recommendation also applies to Confluence spaces.
