NC 12.0.3 News App: OPML Import?

I was very happy to see what I thought was an ability to import my existing feeds into the News App. That initial feeling became disappointment when absolutely nothing happened when I clicked onto the import arrow. Export appears to be working since a dialogue box opened when that arrow was clicked.

Am I missing something? Have I misunderstood to intent of the import option? Or, is it kaput?
