Under "Main" menu, there is a "Play Queue" press that on the righ you'll see the list of songs that are going to be played. On the top it says: Playing from: "The list name" you can click on the list name and follow or waht ever you like to do. :)
So, I was facing the same issue and I found the solution. I couldn't find the current playing playlist on desktop version, so I checked my mobile app. And there it was: recently played. I hope this will help for someone. :)
I can get to the playlist but I can not get to the specific song that is playing. I am using the windows client. Clicking the album art just makes it big or small. Right click does not have an option anymore to go to the song. Now, I have to manually scroll through hundreds of entries to try to find it. It is awful.
