i can't remember which ios update it was but one of them removed the ability to set custom wake-up alarm sound (separate from the generic alarms).

did it pop up a warning? no

did it default to a built-in alarm sound? no

did it just stop sounding the alarm, but still show it as active and selected in the config screen? yes

I simply stopped using the wake-up alarm function due to this. Never figured out how to make it work again.

same. i had multiple days of confusion 'cause i thought i was sleeping thru the alarm / half-consciously dismissing it (something i've had trouble with before)

i'll never trust apple to provide a simple alarm clock again for anything important
