This question was asked in 2019 but the topic was closed.
When I’ve played music in the Sonos app on my phone sent to one of my speaker sets, if someone calls me, it immediately starts playing again even days later. I Airplayed some tunes to kitchen setup on a Christmas Day. It’s now 28th December but even now, every time someone calls me, I get Grace Jones again!
This has persisted for several software and app updates and has been a thing for about a year. I think I can cure it by fully closing the app in my phone but it’s an odd behaviour and, as I’m sure many people do, I don’t routinely close the app, just leaving it in the background. It did this very thing the other night when a teenager rang at 2am for a ride home. I didn’t notice it from the bedroom for 5 minutes and assumed the neighbours were having a party
Any light shed on this would be useful.
