I've downloaded version 6.4 of the app. What a mistake. To anyone who is about to do it, DON'T DO IT IF YOU LIKE YOUR QUEUE.
Sonos please put it back how it was. This new app is so awful I am considering selling my entire Sonos rig (6 pieces!) and walking away from you, after what was until this week, many happy years.
Touching on a track because I want to play it, or add it to the queue (the queue that I DID WANT), does not mean I want to delete the whole queue and replace it with the entire album (which I DON'T WANT) which the newly added track comes from.
If I wanted to delete my queue, I would delete it. If I wanted to add the whole album, I would add it using the play all function.
You've just taken something intuitive and user friendly which worked so well and turned it into a worse than hateful mess.
PLEASE UNDO THIS AWFUL, HORRIBLE CHANGE.
