Currently, exporting Forecasts and Simulations to CSV is not available.
This features will soon be enabled, but in the meantime feel free to send simulations to other Levers users with a sharable link.
To send a sharable link, in the forecast table view, under "Simulation Options" in the upper right corner, select "Get Sharable Link." The link can be access by anyone that has been granted user access to that specific Levers account.
