My Issue

When I try to link the Spotify service to Cortana, a blank page is shown and nothing happens after. 

I am able to connect to other services such as LinkedIn or Google.

It seems that the calls from Cortana are not answered by Spotify.

Does anyone know how to fix this situation? I Paid for premium just so I could use this feature. If I can not, there is no reason for me to use this application.
