For my project in the past we had one board used by one team. This board has story swimlanes enabled and visible in the scrum board view.
Since we split the team in two we have created two additional boards, one pert team but still for the same single project. The separation between the teams is based on the label. The parallel sprints are enabled in JIRA and story swimlanes are set per board.
When I navigate to the scrum view of the new boards I can't see the story swimlanes. I can see them when I change them to be e.g. assignee based.
For the original board, which shows all the issues for both the teams, I can see the story sweimlaes properly.
Any idea what could be causing the issue of story swimlanes not showing in those two mentioned boards?
