I’ve had Sonos in my house since around 2015 and I’ve noticed the app has, in the last few years, become less and less reliable. It’s gotten to the point where if I want to listen to music I have to tickle the app (by accessing it then shutting it down a few times) around 20-30 mins before it will actually find my system. I can be standing a metre from my router and one of the speakers and it still can’t find it. I give up trying, come back in half an hour or so and it’s finally managed to find it.
So essentially it takes 20+ mins for the app to turn on. It was never like this until a few years ago. What’s changed ?
