Siri doesn't answer me while alarm is going
I set an alarm at 11 pm today. The alarm started right at 11 pm, and it kept going. I shouted, "Hey Siri", Siri didn't reply to me. I shouted several times but there was no reaction from Siri.
I googled, it seems that I can use “Hey Siri, stop timer” to stop the alarm. But why it doesn't work for my iPhone? Any suggestions or solutions?
