In our organization, there are two Scrum teams, say Client and Server team. Both teams require testers, and we have the single QA team to support this need. It works well with JIRA.
However, I meet issue when we start to leverage Portfolio for planning. It's straightforward to create Client and Server team and assign Client board or Server board to them. I also create a QA team, but I'm not able to assign both Client and Server boards to them. The result is Portfolio cannot assign the proper sprint to QA issue(s).
