Multiple default views not working

I see that the last comment on this was a couple of months ago but I'd just like to chime in that we're experiencing the same behavior.  We've got a library with a top level view of All Documents and then within the top level folder there are sub-folders that are assigned to different default views. 

I used the example outlined in this link - https://camerondwyer.com/2014/01/06/harness-sharepoint-default-views-at-different-navigation-hierarchy-levels-to-build-more-appealing-solutions/#customfolder

As others have pointed out, this works well in Classic View, the issue is that we are using Modern View.

I hope find a solution by continuing to search, but for now the issue persists.
