I used to be able to play these Rob Bell Robcast podcasts (https://open.spotify.com/show/5zUb9oalsHnKDMHIWEaiEp?si=73e8095d4b394661) through my Google and Amazon smart speakers but no more, unless I start it from the Spotify website. Instead, they play something in Greek (I think) or some amateur movie review podcast (neither of these have I ever selected). Then the website switches to that other stuff I don't want. How can I fix this? One option could be for me to create a playlist with just the RobCast feed, but I see no way to add a podcast feed to a playlist (just individual episodes).
