David ParnellYesterday the alarm on my iPhone didn’t go off. Did I sleep that soundly that I missed it? Ditto this morning but I was awake to see the banner come up but no noise. I checked the settings - the only one that should silence an alarm being if it is set to only vibrate, and all was as it should be. Eventually I found a suggestion to re-boot the phone. That worked! Has anyone else experienced this phenomenon? Like most folk I need to be able to rely on an alarm and after many years of using my iPhone my confidence is shaken. It is an iPhone XR.
