Great. So I just upgraded to Plex Pass and did not get what I was after… 
Also, not so impressed by a company that takes money and leaves a forum as the only support. But, I digress….
Plex for Android shows that I have shared “Media” but displays nothing. Plexamp for Android shows the library of music that I shared but not the playlist that I shared. And, yes, I can view the libraries.
My friend can see the shared playlist in Plex for the Web on her Windows PC.
Seems like Plex has a lot of work to do.
