The overview is gone with this downgrade. I’ve stopped using the desktop dashboard page since it has changed, because it has become useless.
My tip is download the green shopify app and the dashboard looks more or less like to old version. You see your total sales, you still have to click if you have more locations to get the sales info seperately. And pay-out is two click away. Not ideal, but maybe Shopify will return to a user friendly dashboard.
