Please QA your app with the latest KEF firmware – KEF Control Review

It’s ridiculous that the main control app can’t connect to $2,000 speakers. On firmware 4.0 it’s impossible to upgrade firmware, change speaker settings for the KEF LSX as their app can’t find the speakers on this firmware - despite them being on the same stable Wi-Fi network that works perfectly for airplay and Spotify (and the app fortunately/unfortunately being able to find them on the original firmware 2.0).
