Hi all. My app keeps freezing on my iPhones (one an X, one an 8) and my iPad. The controller works fine on my laptop (working wirelessly). Everything is updated; and I did a system reset as well. The issue is this: if I open the app and start using it it works fine; if I switch to a different app (or even just go to the phone or iPad home screen) for even one second, when I return to the Sonos app it will play for one second and freeze. Any ideas? I submitted a diagnostic: 1966087381.
