Qobuz connect does not work

Qobuz connect does not work with my NAD C389. The device displays in the Qobuz app but there is no output. Tracks skip every 3 seconds on the Quobuz app. On the Bluos app, I cannot access my Qobuz account and activate the service as the app does not recognise my credentials when I try to log in (even though I use the usename and password that I use to access my Qobuz account). 

Any solutions?
