For months I have had problems with speakers disappearing from the app and then reappearing. I would try to play music in say 4 rooms, and it would play in 1 room but not the others, then all of the rooms, and then stop randomly and one of the rooms would disappear. So so so frustrating.
I have a big range of speakers - Ones, One SLs, Era100s, Era 300, Beam, Subs, Amps, Connect - all over the house.
I thought it was my new Unifi network so i spent ages modifying that but still I had the issues.
Then I realised the most common issue was in a room with a Beam. I just upgraded that using upgrade credit to an Arc Ultra. AND MY ISSUES HAVE ENTIRELY GONE AWAY!!!!
I can now use the app like the good old days - all my speakers are there (including another Beam in a different room) and I can add and remove rooms from playing music and it just works. I can change volume - AND IT LETS ME DO SO STRAIGHT AWAY!!
I am so happy and wish I had upgraded that Beam months ago. I have no idea what this has done or why this one Beam had so much impact on my issues, and why it works but it does so I thought I would share.
The Arc Ultra is a massive upgrade by the way!
