My Sonos Beam keeps losing the connection from the app and from my Spotify list of devices.
The Beam is still connected to WiFi as I am still able to use the Alexa voice control to play music from Spotify or Amazon.
To find the Beam again I would have to keep switching off and on the router. The Beam would reconnect with the app again but then the next day would have disappeared again. Very frustrating. It was obvious that something was happening overnight for this to occur again and again.
I have since switched off the option for the Beam to check for updates automatically overnight. Since I have done this, the problem of the Beam disappearing from the app and the Spotify list of devices has been solved.
So although this solution works, I now have to manually check every now and again for updates. This isn’t ideal and I feel it must have been in an update for this problem to suddenly occur. I had had the Beam for 6 or 7 months with no problem like this at all and my Wifi network at home is stable and with a good signal.
