Bottom Tabbed page issues

I am trying to use a bottom Tabbed Page for Xamarin Forms (Android).
I have this error message:
'IPlatformElementConfiguration<Android, TabbedPage>' does not contain a definition for 'SetToolbarPlacement' and no extension method 'SetToolbarPlacement' accepting a first argument of type 'IPlatformElementConfiguration<Android, TabbedPage>' could be found (are you missing a using directive or an assembly reference?)
Anyone have the same issue here?
looks like my 'Toolbarplacement' is missing
