I have already commented that I own a Roku]. Well one of the features of this device which I wanted to have enabled, was its Spotify Channel, so that I could stream music through the Roku.
Unfortunately I have already observed, that even though the Android Spotify app is well-managed, and allows me to manage my playlists, the company has not put any serious effort into getting their Roku Channel working.
Since it was not my purpose just to subscribe to one more music-streaming service, but rather to have this on my Roku, I felt that I had no choice but to cancel my Spotify subscription.
In fact their support for the Roku has deteriorated, and not improved.
