Inherit Navigation for modern Team Sites to Subsites

Hi,

we are building up an intranet solution based on "modern team sites" using SharePoint online (first release).

We created a SiteCollection and set up some "modern" pages. Within those pages you see a different navigation than for classic pages within the site.

If we create subsites we want to inherit the "modern" navigation items to the subsites or use managed navigation. But neither of those settings is affecting the modern pages within the subsites.

--> How can we manage the navigation for modern sites/subsites from one place?

Regards

Christian
