its now under "menu" (pop's up > lower left corner).
but by the way: I'm missing the refresh button ...
It will be. ePO 5 and above uses browser refresh. You can use browser refresh the console page or can use server settings (server settings->Dashboards) By default, refresh interval will be 5 minutes but can be modified.
Thank you Meforum
