Amazon Music Problems

Can someone explain why i have lost the ability to control Amazon Music that's playing on my phone with my watch. 

I can no longer, see the current track that's playing, skip back or forward, pause or control the volume. 

If I connect to Amazon on the watch it just asks for headphones to be connected. 

Is this a deliberate move or an error in the latest update. 

I find this very annoying and I hope this function will be reinstated. 

I look forward to hearing your response
