The ‘All Work’ section (or tab) of a Team should show the Portfolios shared with that Team. Currently, it shows all the Projects & Templates that have been shared with that Team.
From the Teams page, you can access Projects, Goals & Templates but you can’t access Portfolios. It’s important to all work shared with the team in one place, including Portfolios as these are an important part of how we manage & do our work.
Don’t forget to click the title to scroll to the top and vote by clicking the Vote button (like I just did); that’s the quickest and most effective way to express your support for a request.
It was only a few weeks ago that Portfolios could be shared with Teams (instead of just individuals), so perhaps this is being considered as what Asana calls a “fast follow.”
