I recently upgrade my 4 roku boxes to the new ones because they are the only kit that let me have NowTV, Amazon prime video, Netflix & Spotify on one box. Now I have to invest in new equipment just so I can access Spotify on my TV. The first app was great, then playlists got removed which was annoying but I could still access all the music. Continued use of the existing app would be great until a new solution is found!
