Can't share a song via Messages

Hi, I have recently got an iPhone 7 Plus and subscribe to Apple Music.

When I listen to a song I want to send to a friend to listen to I click the three dots ... which opens up the area to choose how I want to send the link to the song. I click on the Messages icon and after about 20 seconds delay a new message window opens but with no link to the song, it's just a blank new message.

This all used to work perfectly on my iPhone 6S.

Can anyone offer any advice as to what is wrong here?

Thanks.
