I have had a Sonos Play 3 speaker for a while now and control it using the S2 app on my iPhone X using the latest ios 16 software. The app has always been slow to start; now however, with the speaker on and working normally and playing music from a internet radio station, when I launch the S2 app, it comes back with the message “unable to connect to Sonos - let’s fix it”. It then takes me through a routine which involves re-booting my router and then it finds it. However, if I then put the iPhone down and it goes into standby, the app again fails to find the system; so back to square 1.
I have found that, if instead, I launch the S1 app it finds my Play:3 OK but says “incompatible”, but if I follow the link “open Sonos S2 app” then the S2 app starts to work ! Still no good, because if I come back to the S2 app later - it’s failed again.
There’s a solution on this community web site which says turning off “Private wifi address” in ios 14 is the solution, but this does not work for me.
My broadband is Fibre to the Home - very solid, and the wifi connection is very strong and only 5 yards to the Sonos speaker. When working the app reports my wifi is a good signal and using 5G channel 44
Can anyone help please?
