Manage multiple plans effortlessly with the new Portfolios feature in Microsoft Planner

Thanks for the detailed overview Meet_Sanghvi . I have setup the Project / Planner P3 License, and still after a few days, when I select 'My Portfolios' through the Planner App in Teams, I see this error "Looks like you don't have the latest portfolios solution installed. Contact your admin to fix this".

However, even an internet search provides no results to this problem. Is there a suggested solution to get Portfolios working? 

Thanks!
