My Question or Issue

Hi my name ist Thomas.

I created a Playlist called "klausthomas"

i want that alexa when i say "Alexa, READ"

I created a Routine.

First he dimm the light and then he say, have fun at Reading.

All works but when i give alexa the command to use my Playlist.

She say i could find this playlist on Spotify.

When i ask Alexa Direktly to my Playlist she also dont find it.

i have 5 other playlist all the same with other names

there it works.

what is the problem.

I made the playlist public that doesnt help.

I hope someone  could help me
