I did. Maybe I missed the fine print. It seems like you can dismiss warning and alarms.
"You can wave your hand in front of Protect to dismiss the beeping — essentially, like pressing snooze on an alarm. As long as the situation doesn’t worsen, then your smoke alarms will never sound."
"For severe issues, Protect may opt to bypass the "heads up" warning and simply sound the alarm"
Still it doesn't say that this hand wave feature will stop working in these severe situations.
Ofcourse, I am sure they will iron things like this out before shipping.
Did you read the description at all? You can only dismiss warnings not alarms. You cannot dismiss life threatening situations.
