I use the bedtime alarm setting on my phone (iOS 14.4.2), and this morning the bedtime alarm went off even though it wasn't set for Friday. My work schedule varies, so I change it at the beginning of the week. I saw the bedtime reminder pop up last night, and checked to ensure that the alarm was not set to ring, but it went off anyways. It did not go off yesterday, which also wasn't scheduled. I'm pretty sure this happened a few months ago, so I can't say it's the latest iOS. Has anyone else had this happen?
