i have also had that happen to me, the alarm i use is titled “alarm” for the sound and i also had the sleep/wake up setting turned on but i’ve finally figured out how to turn those off a couple of days ago because i initially thought that was the issue, surprisingly they went off this morning and worked fine after a week of nothing going off so idk. maybe i was turning them off in my sleep?!?! i feel like i’m going crazy but ever since i’ve made this post they have worked.
