Hardware approx 10 years old, running the S2 OS. The old app works absolutely fine but the “new Improved” app on either the iphone or iPad refuses to recognise any of them. Luckily my better half has not updated this awful app on her devices or she’d be marching straight to Sonos HQ.
For now, having to control every speaker in the household via her device(s) or via a Windows laptop.
Sonos should get the team that tested this application to issue a grovelling apology to everyone affected and sort this one out asap.
