In my setup I have 4 teams with a shared backlog. Each team has their own sprints so that at any given time I have 4 parallel sprints running. In the "old" Portfolio for JIRA I was able to assign sprints to a team so that issues assigned to a team would be planned automatically for this team.
I'm now looking for similar functionality within the new Advanced Roadmaps interface. So far I have looked in the Teams settings (where it used to be), the Portfolio settings, View settings, ... and that's where I am now.
Could it really be that this functionality is not supported yet and I have to go back using the old interface?
