@mind4wine,
Maybe try this quick/simple two-step method below…
- Step-1: Search in the Amazon Music App to find the playlist you want to use as your alarm and just hit the + sign next to that playlist.
- Step-2: Goto the Alarm creation screen in the Sonos App - select ‘Music/Amazon Music/My Music/Playlists, where you will see the playlist from Step-1 and select it as your alarm.
The playlist selected will then be what plays at the time/day you set for your alarm.
I personally find the Sonos App easy to use with Amazon Music. It works well for me, at least.
I hope the above assists.
