Have been experimenting to try and understand/resolve the nature of this problem but not able to, so need some help if possible!
Have 3 x Play:1s, recently noticed that only a single Play:1 was visible in Mobile App (S2 on Android, Samsung S21). However, I have found that all 3 are visible in Controller App on Windows 10.
The speaker that was visible was connected to a BT Smart Disc Extender. If I ensure the mobile phone is connected to the Extender, it doesnt have any impact. If I disconnect the Extender, the speaker disappears completely and Sonos reports no active speakers. However, all 3 remain active in Sonos Controller App on Windows 10.
If I connect one Speaker to the router directly via Ethernet, with the Extender still turned off, all speakers come up and are visible in both the Controller App and the S2 app on Mobile.
If I then remove the Ethernet cable, the speakers remain connected and visible in both apps for a short period but eventually they all disappear from the Sonos S2 app, but remain visible in the Controller app. All speakers show as connected directly to the Router when checking the router config- I therefore dont think its a connectivity issue for the speakers themselves but more about visibility?
I initially thought the issue was related to the Disc Extender, since this is the speaker that generally remained visible whilst the other two, connected to the main router, disappeared. However, if I eliminate the Extender, then all of the speakers disappear from the S2 app which would seem to indicate that the issue is with the Router rather than the Extender. Equally, I do not get any issue with the Controller App, in any circumstance, which would seem to indicate the issue is a device issue rather than a Router issue?
Both devices, laptop and mobile, are connected to the Router via 5Ghz.
I suspect if I move all 3 speakers nearest to the Extender, so that they are all connected to that, then perhaps all 3 will be visible in both the S2 app and the Windows Controller app- however, I see little purpose in doing that, as I dont want the speakers located together permanently and I cant force the Sonos speakers to only connect to the Extender rather than the Router.
Any suggestions or ideas I can try?
My workaround may be that I leave one speaker permanently connected via Ethernet to the Router.

Ah. The new Private Address feature in iOS! Yes, this has been causing problems for some. There’s a thread about it here:
I believe a reset or reinstall of the Sonos app, followed by reconnecting it to Sonos (with the Private Address feature active) will solve the issue.
It’s not confirmed, but I believe the change of the phone’s MAC address since the first connection of the app makes your Sonos system mistrust it.
