Update: Document Sets in Modern Document Libraries

LincolnDeMaris, when updating a document set content type (like adding a new allowed content type), here is the behavior:

For existing documents set folders created before the update:

• The new content type will only be available at the root of the document set folder. It will not be available for folders inside the document set folder.
• To be able to get the new content type inside these subfolders, I need to switch to classic, open the document set folder and perform an "Update documents set". This command is not available in Modern. I want to make sure we will get this option in modern unless adding a new content type will be reflected in subfolders without performing an update.

For newly created documents set folders: It will work as expected.

There are still other issues with documents set and it looks like there is no more tuning on this. Can you give us the status for modern documents set development? Is this completed for Microsoft?

Thanks.
