Sharing a link directly from youtube app iPad into OneNote can reach into one folder hierarchy level

Trying to share a YouTube link from the IPad . However within OneNote my folder structure has 3 levels

mynotebook -> section1 -> mynotebook

however for direct sharing from the iPad YouTube app , I can only share to mynotebook -> section1 

It does not allow me to share to a specific notebook within the above folder hierarchy Shown.

And this feature depends on the YouTube application for the iPad, relies on Apple sharing feature as well as possibly Microsoft implementation. I’m speculating at this point.

Can someone from Microsoft highlight what could be going on ?
