I use my (single) Balance as speaker for my BS 9000 via BLC. The Balance is relatively new in my set up and I experienced the same behaviour you are describing, e. g. when I came back home after a business trip and tried to join the Balance with the BS 9000 / BLC. Unplugging the mains of he Balance usually solved the case, one time I reset the unit. Another issue I experience is, that the app on my old iPhone 7 does not show the my buttons (the respective radio stations) and the sound setting of the Balance. This is also the case on my iPad which is solved through the above described procedures. I can join the BS 9000 / BLC with my Emerge as well. The Emerge does not show ML sources. I can join the Balance sometimes manually, via app and other times both ways. In the App all my BLCs are displayed as well as the other NL devices tapping the Balance, but all other systems, Mozart or not, only show the existing NL units. Connectivity of Airplay sources is working also.
Kind regards,
Rolf
