As a Spotify Premium member, I have had a very frustrating persisting issue with downloaded playlists on my apple watch. Specifically, once I get to and finish the last song on my downloaded playlist in my apple watch, I am unable to further switch and listen to different downloaded playlist music or different music in that very same downloaded playlist. In effect, my apple watch spotify app is essentially frozen/fixated with the ending of that last song. Even if I turn off and restart my apple watch or refresh the watch app itself, spotify on my apple watch will not allow me to listen to any further music.
