My alarms on iPhone 15 have been going off silently with no vibrations, usually after I snooze once or twice. I have several alarms set to wake me up in the morning, but after snoozing them (and once another alarm starts to go off) NONE of my alarms work anymore! They just go silent, and I can't even press my volume button to snooze it anymore- they just become frozen!
This happens DAILY, and my alarms will stack up and appear to be "shaking" on my lock screen as if they are still going off (but silently). This started happening about 3 years ago, and despite keeping my phone updated, it has never been resolved. As someone who is narcoleptic, I NEED to have multiple alarms and be able to snooze them until I'm conscious. I've tried deleting alarms and making new ones, and I've checked both sound and haptics AND do not disturb settings to attempt to fix it. PLEASE help- this has been detrimental to my work and personal life.
