Sonos Alarms not using Plex for source
Background: I contacted Sonos support about this issue in July of 2016. They have recently replied that the issue resides with Plex, that they have contacted the Plex team and that the plex team acknowledged the issue was with Plex and has requested that any customers contact plex in this forum.
So to describe the issue:
From the Sonos app:
I am trying to add an alarm based on a plex playlist and the UI doesn't allow me to pick one of my playlists. Rather it asks to add an alarm based on all playlists. I would expect to be able to navigate further into the playlists folder. This also applies to the "By Artist" and "By Album" folders.
This issue seems to only apply to the alarm feature. I can navigate into those folders when I am browsing my music.
