Emergency Alert can't be silenced
Emergency Alert on 10/4 set off an alert on my dad's iPad that can't be shut up. His iPad is not connected to cell service only WiFi. about every 2 minutes the alert will come on for about 10 seconds and then stops until next time 2 minutes later. I cannot find a way to turn it off. there is no visual notification on the screen when this happens. Unfortunately he lives in another state so I direct him over the phone. His iPad also does not respond to a shutdown command. If anyone has and ideas on this problem I would welcome it.
iPad, iPadOS 16
