I did have my share of problem too. But everything is working fine again. I never managed to get ML sources visible on a Mozart device directly (BL8/BL28) though, I was surprised to read that you hade it available on your Balance. But that was no issue for me, because I could access them though other devices. What changed is the BLC sources can directly be started on the BLC in the app and then the BLC can be joined by other devices (Mozart also). And yes, sometime the Mozart device doesn't seem to follow the JOIN command. But what does help is to join manually. Mostly thereafter it works fine again (or first start a source on the Mozart device and then join, thereafter it should work again as normal). note: I have an escape route - I programmed my Halo/BLI to directly start any ML source on any device (also Mozart). I did have lengthily discussions with B&o about it.

The short answer is: they have f*ucked up the SW 😡 If you want the polite answer: they have choosen not to implement this feature (ML sources accesable directly on NL/Mozart devices)…………..reason unknown 🥹 MM

Thanks MM and Carolpa. In the past, I was able to start the ML source on another device and join the Balance via the app. Yesterday, this wasn't working.  It would only boop or double boop. If my memory is not too faulty, the app has changed so that instead of it showing the converter linked to the BS1 (for example), it now shows the converter as the "master" link source no matter how the source is started, and all the other devices are linked to it.  Subtle difference and probably makes more sense, but I was afraid they messed up Mozart with this enhancement. Today, it is working again.  Go figure. This is also how I listen to lossless WMA files from my BeoMaster 5 disk. With the Balance, I can select a song and it plays the song and stops.  With the BS1, it plays the song and the next and the next, etc.  So I start the music on the BS1, mute the volume, join the Balance. Although to be honest, I generally just stream unless I'm feeling "old school". I would guess they dropped ML support in Mozart because, in my experience, every manager and software developer hates backward compatibility so they saw their chance with a "next generation" product to drop it, and they did. I mean how far back does backward compatibility need to go?  Customer says "forever".  Manager says "never". They fight it out, and we get what we get.

OK! In terms of backwards compatibility B&O has always been special.......one of the things that many a costumer have loved them for. So - it is more a question of them wanting to keep their old costumers - after all they would still want to spend money on things....if they would work in their current setup. MM
