Hey, Tommi!The new navigation experience also introduces the new "Insights" section that will allow you to build custom reports and combine these reports to an elaborate dashboards that you can even share externally.The Revenue Forcast report is currently being worked on and is not yet implemented within the Insights. We expect this to be added soon. During the migration phase, we allow people to switch back and forth between the new and old navigation experience.We are sorry not to be able to offer this functionality immediately. Keep an eye on this channel: https://community.pipedrive.com/feed/whats-plannedWe will be adding an update about the Revenue Forcast report shortly.
I had the same problem - you need to switch back to the old view @Tommi Timoharju
