I have many Sonos speakers throughout my house and use a playbeam grouped for a radio alarm. Until the last update, it was working perfectly for that alarm (yes, have a include grouped rooms switch set toon for that alarm and all speakers are actually grouped). Since the update to the most recent firmware, the alarm will ungroup the speakers when turning on, making the radio play on the one speaker only.
I have unset/set that group function, as well as deleted the alarm and configured again, to no avail.
I have a second alarm set on a playbar, also with include grouped rooms switched on, and that continued to work after the update.
Anyone else with this issue?
