I had started using the Sonos Alarm feature.
It never worked properly as often the Sono beep was playing instead of a song, sometimes the controls from the notified were not working unless I was first opening the Sonos App etc... Despite this it was at least somewhat working even if this is not the experiences you'd expect from a product like Sonos that it is not famous for being cheap.
The newest issue, however, is that apparently after some updates the notifications on lock screen and on the main screen are completely gone.
It is not possible to snooze or dismiss the alar. Anymore. The only notification present displays the Sonos controls as if I was simply playing music (play, pause, next, etc...)
