First, the majority of posts on the new App where questions. Then, bug reports and complaints became the dominant topic. And meanwhile, everyone just asks how to roll back.
And Sonos? First, they post how great the new App is. Then, they say they "listen" to feedback. Meanwhile, they even have a schedule when missing features will be added again. No comments on the real bugs.
My interpretation: Developers are far behind schedule and now just enforce everyone to be beta tester in order to get enough feedback in a short time. A voluntary beta tester would meanwhile have given up.
