Alarm goes on without setting an alarm
Hi. My alarm goes on at the same time every morning even if I have not set an alarm. This started when I set up my iphone 11 from the cloud after migrating from iphone 6. The alarm goes on at the same time I had it set up in iphone 6 only for the weekdays. It happens the same exactly time everyday except from weekends. I have no bedtime set at all not reminders, no third party alarm app or anything similar. Finally, it sound only two time and it stops but the notification stays on the screen even if silent. I also erased the phone and set it up again from the cloud but same situation.
iPhone 11, iOS 13
