Apple Music playlist names won't display in Sonos apps

Just what the title says. The names of my Apple Music playlists are just blanks, just white space. This is true on my iPhone, my iPad, my Macbook, my desktop controller (Windows) and my Apple Fire tablet. All are S1.

I posted a message in a Sonos community. One user said "This is an Apple change to SMAPI that broke the S1 app." Is this true? Will Apple fix this?

This is only a problem in playlists. Under Song or Albums, all titles are displayed.

With Sonos, I cannot update to S2 because I have two pieces of older equipment that are incompatible with S2.
