The release overview of Version Sync for Jira has the same function as the Jira Releases screen. The important difference is, that it refers not only to the issues in this project but to all issues which are in the synced versions.
This is how you navigate to “Releases – Version Sync for Jira”.
The “Releases – Version Sync for Jira” menu item is only displayed when the project is in a Version Sync group.
Company-managed (classic) projects/Team-managed (next-gen) projects
Select any project which contains the synced version
