Backbone adds a Sync Info Panel to the view issue screen of all issues in your JIRA system, and displays a variety of information on the issue's Backbone synchronizations:
The issue key of the partner issue
Issue sync Status
Details about the synchronization status of this issue.
UP TO DATE All changes have successfully been synchronized
PENDING You have made changes that have not yet been confirmed as successfully synchronized by the partner instance
ERROR There is a problem with the synchronization of this issue, and the synchronization has stopped working properly. If you hover over the error message, a tooltip will appear that shows you if the error is in your instance or the partner instance
Details about the status of the synchronization of this project. For more details, see synchronizations overview.
The time when the issue last received changes from the partner instance or sent changes to the partner instance
Hide/display the panel
By default, the Issue Sync Panel is visible to all Jira users – but Jira or project administrators can define which users can see the panel, and who can't.
You can enable/disable the Issue Sync Panel on a global level – or for individual projects – by navigating to Project settings > Issue Synchronization and clicking Enable/Disable Issue Sync Panel for all projects.
When disabled, only users that have the View Backbone Issue Sync Panel permission (this is configured like any other JIRA permission) can see the sync info panel
If you are using Jira Service Management, make sure the synchronization user is member of the Jira-Servicedesk-Group to be able to see the sync info panel
