I have a list in a SharePoint 365 site; it is set to classic experience and has several public views created. When I copy the list (either in the same site or a different SP365 site), it creates the copy with default experience and only the original All Items view works - none of the custom views work. They are there but when selected an empty browser page is presented. When I change the list to use classic, the views still do not work. I end up deleting the views and recreating them - then they work! Any ideas why the views don't work when the list is copied?
