When I use the "Hey Siri" feature to enable an alarm it usually works. But recently I've encountered a problem. The conversation with Siri would go like this:
<me> Hey Siri, wake me up at 7 20. <Siri> Your, 7:20 alarm is on. <Siri> (short pause) <Siri> Sorry Jozef, there has been a problem setting up your alarm.
And indeed the alarm is not turned on for 7:20. It would work for other times, ex. 7:10 (regardless whether an alarm at desired date exists or not).
Is there any special case when Siri can not activate a specific alarm?
This is not a problem with Internet connection (I have one) or understanding of what I said (the text is interpreted correctly and Siri actually seems to have turned the alarm for a short moment).
