Hi @Ivan12093
I can confirm the details for my four (4) Sub 4’s bonded to my three (3) Arc Ultra’s with Era 300 surrounds do not appear.
However, I can see details for my three (3) Sub-Mini’s bonded to my Beam2 with Era 100’s, Sonos Amp with turntable/3rd party speakers and Era 100 stereo pair. I also see details for a Sub (Gen3) bonded to my Era 300 stereo pair.
Please update this thread when you hear back from Sonos Tech Support (STS). Feel free to add my comments to the investigation. I’ll try to contact STS as well as they escalate things when multiple concerns about the same oddity are voiced.
