I haven't used the Sonos app for a while as I have been playing from Spotify to the speakers so cannot really say with confidence how long this issue has been around. However, since using the S1 app, so I suppose since march, it has not been able to find the Sonos system. When attempting to connect to an existing system, it prompts me to press the mute and vol+ buttons, which I do, which the app recognises me doing, but after a couple of minutes of scanning, it fails to connect. On Android it tells me it has connected and returns back to the setup screen.
I have 4 1st gen play 5s which I have owned from new for around 9 years, one of which is connected via ethernet.
Spotify is still able to communicate with the devices when playing via my phone and recognises the stereo pair I have, so something is working, just the official app seems to struggle.
I noticed when logging into my Sonos account that the devices were last registered 14-16 march 2020 but not sure what that actually means.
Any help would be appreciated.
