Alarm doesn't work. – MEDION BT LED Bulb & Speaker Review

The alarm feature doesn't work correctly. If I set the alarm and my iPad is open, it works great. If the app is left OPEN and the iPad locks, nothing happens. No alarm, late for work, lose my job. No good. It's a shame because it's a cool bulb and the other features of the app are nice, but the most important feature doesn't work at all.
