If you have a routine that plays a playlist on Spotify, and that public playlist name has an emoticon, it will not find the playlist
Here is an example playlist:
https://open.spotify.com/playlist/3MotlPudfwBibX01JCjVs0?si=4tc7mUmhSm6IgNOUC_2zRg
It has a wine glass emoticon in the title so Alexa will report it cannot find "Soft French & Chill"
