Play queue has disappeared

[Shwa]

The play queue no longer seems to be accessible so I can't tell what tracks are queued. It used to be accessible from the now playing screen, but clicking a track makes the whole screen concern the current track, with no reference to the play queue. The generic support faq refers to the old interface so wasn't helpful here. I can't post the version number because Spotify decided to use numbers that look like ip addresses. 

Any ideas?
