I have an Alexa Echo. It will play music from my premium spotify. I can play music from my phone or ipad. However when I ask it to play any spotify playlist in my library it never finds it. It can find a similar named playlist and offers to play that but never on in my library. I have a playlist called Birthday, I ask Alexa to play spotify playlist birthday. It will ignore my birthday playlist and play a random public playlist with birthday in the title. I have tried multiple ways to ask Alexa but nothing work. I can play the playlist if I slect it on my phone and send it to the Alexa speaker directly. i would really like to be able to choose my own playlists.
