Has anyone else got this problem?
A new album/song comes out on spotify and it takes 3-4 days before alexa can find it. My example right now is Feeder and the album Tallulah.
"I couldn't find Tallulah by Feeder on Spotify"
The only way I've worked how to do it, is by starting the album on my phone and then telling Alexa to "play spotify"
You should take these issues to Spotify tech support and/or the makers of the Spotify skill.
