When I save a portfolio item with the "Create project on save" box checked, the project gets created, it appears under "Relationships" on the portfolio item, and the Project button appears on the portfolio item taskbar. But, when I click the Project button (via roles or tasks) the system does not navigate to the project. Nothing happens, no errors, and the system just remains on the portfolio item screen. The projects can be accessed via Fiori tiles, but not via portfolio item screen using the Project button. Does anyone know why?
