I came back from a work trip, and when I came home I noticed that Sonos needed some updates. So, I did. But now the widget of the android app is gone, but most annoying of all, I cannot use my music library anymore. I can update it, but I cannot browse it's folder sturcture, nor can I search it's contents. I have a huge library on both my laptop as on my phone, with songs that arent on Spotify. 

Main points:
1. I have this music to listen to.
2. Sonos has made it impossible to listen to.
3. I'm now unsure what the advantage is of using Sonos, opposed to just plugging a mini-jack into one of my devices?

So, Sonos, get your shit together, and make sure users can access their libraries again. And maybe, if your developers might have some time left, let them develop a widget. But without that library function all of my stuff will go right into the bin.
