Timer and Alarm not working after ios 15.4 update
About a week ago, I noticed that my alarms and timers have not been going off. This has caused me to sleep way past when I should have been for multiple days in a row and it's extremely frustrating. I tried messing around with the settings tonight and it is simply a glitch in the app and not user error. I have gone to setting > sounds & haptics > and turned the ringer volume control all the way up. I have also turned on the vibration. Now when I go into the apple clock app, and I set a new timer with the "radar" sound, it will go off but the sound it so quiet and it plays from the top phone speaker beside the front-facing camera, not the media speakers near the charging port. The vibration does not go off for a timer. A similar thing happens when setting an alarm. When I create a new alarm or turn on a previously created alarm, sometimes the noise and vibration just fails to play, sometimes it rings and vibrates for 2 seconds and turns off (without me touching my phone), and sometimes the alarm plays normally. This inconsistency is very troubling to me as I cannot keep sleeping past my alarms and fail to get up for work. The only thing that I can think of that has changed in the past week since my alarms/timers have been failing, is that my phone updated to ios 15.4.
