Playlist issue after Windows 10 Creators update

Many thanks for getting back to me.

I checked, and it is still in MTP mode.  While I was in Settings, I looked through all the other options in System Settings, but couldn’t see anything that could explain what happened.

While I was in settings, I just checked the version number as well - it’s V01.01.21P.  I wonder if there might be an updated version, or a new driver to install that might be worth trying?
