Label views show all issues under a specific label.
Label views show you all the issues associated with a label. While team-specific label views only show issues associated with the team, you can create custom views to view issues with identically named label across all teams.

To view a label view, click on the label from a board, list, or issue view. You can also use O then L to launch a menu and select the label view. You can favorite label views as well as filter them. Team-specific label views only show issues in the specific team associated with the label, whereas workspace label pages show issues associated with the label from all teams.
If multiple teams have a a team-specific label (e.g. Design), and you want to view all issues with the same label across these teams, it is possible to use filters and custom views to do so.
To set this up, create an All teams view, then apply a filter for the specific label. Make sure the label is spelled exactly the same across all teams, though capitalization and label color don't matter.
