Sonos Alarm Spotify not working

Hi, 

I use the latest Spotify App on iOS 18.0 and setting up the alarm with a Spotify playlist does not work

wether I use and existing alarm or create a new one the following happens:

1. Open Edit Alarm → Music
2. I search for my playlist 
3. Select the playlist
4. get “Set Alarm music” promt - “ would you like to use”XXX” for your alarm music
5. tap “OK” 
6. App goes back to Alarm overview “Alarms” ( I can see it briefly stepping back in “Edit Alarm”, then back to overview “Alarms”) 
7. Alarm music is not changed / still Sonos Chime

I tried reconnecting Spotify, reinstall App and its Spotify premium
