Adding tracks on watch is 3.1.1

Hi everyone!

I've just updated to Watch OS 3.1.1 and when I'm listening to Beats 1 radio I no longer seem to have a "+" to tap to add the track that is playing to my Apple Music library.

There is now a volume control where the "+" used to be.

Does anyone know how I can do this as I used to love being able to add tracks straight from my watch.

Thanks, Dave

 

I've just discovered that I can ask Siri to add tracks to my Apple Music library on my watch which does the job but isn't as convenient as tapping "+".

Also I can't tell if a track is available on Apple Music yet so a lot of times I'm getting told that Siri couldn't add that track.

Previously the "+" wouldn't light up if the track wasn't available.
