Email us. A person answers.
Include your iPhone model and what happened. If an alarm misbehaved, tell us the time it was set for.
The alarm didn't ring
Check that Proof of Wake is allowed to send notifications, and that the alarm is switched on in the app. A phone in Low Power Mode can delay the start of a sound.
The mission won't accept my answer
The mission changes with every wrong answer. Read the problem again rather than retyping the same number.
