This latest update fixed an issue for me with Alexa when I would ask it to play Library Radio (or in other words, “tell plex to put on some music”, ie: shuffle songs).
It now works, when before it would report an error to me.
So to him this may concern, this is good news.
And thank you to the Plex team for fixing this issue, even if it may have been unintentional!
