What is the problem in detail? 

Is there an error connecting Deezer to google home/ assistant as a music service?

For me this still works, but at the moment using voice commands is very buggy.

It’s always worked fine,until recently,it just won’t connect,tried unlinking Deezer and setting up again from scratch but nothing seems to work
