As others, alarms are buggy for the past few weeks. I think it's after the Android 12 update on my Samsung S10e. When I test it, the alarm works. I have missed morning meetings. I thought it was the single alarm and set up a second one for 5 minutes later, but neither of them went off this morning. I am doing an app and system reset, and try to test it. If that doesn't work, I will begrudgingly do a factory reset due to this one issue!
