iPhone snooze goes silent
Sometimes when my alarm goes off I say "Siri, snooze." Usually, the alarm stops ringing, Siri says "I snoozed it," and 9 minutes later the alarm goes off again, which is what's supposed to happen.
But sometimes the alarm stops ringing, Siri does not say anything, and the phone never makes another sound. If I look at the phone less than 9 minutes later, it says it's snoozing, and if I look more than 9 minutes later, it says the alarm is going off. But it's not.
Restarting the phone fixes the issue, but only temporarily.
This issue has recurred through multiple software updates.
