Hi since the new design just got updated i can only see the board twice Board and Sprint Board ,.. where is the list of the backlog as it was showing before?
Are you currently utilizing a Team Managed Project? If so, it's possible that the feature is disabled in the project settings, and you will need to enable it.
To enable or disable the backlog:
Navigate to your team-managed software project.
Next to your project's name in the sidebar, select More actions (•••), then Project settings.
Select Features.
Enable the Backlog feature.
Another way you can enable the backlog feature is by:
In your project navigation, select add to navigation (), then select Backlog.
