In watchOS 7 & iOS 14 there are couple of problems when using wake up alarms in the sleep schedule:
First, when you create a sleep schedule with wake up alarm and wear Apple Watch to bed, the alarm will go off only on the watch - not on the phone and there's no option to choose phone as the alarm's destination. The UI related to this is also confusing: when you open Clock app on the iPhone, you will see the alarm set up but no indication that it won't go off on the phone (until you dig deeper). This is problem because not everybody might wake up to the sound from Apple Watch's tiny speaker.
Second, in order to have an alarm go off with sound (ie. not haptic only) on the watch, the watch cannot be in silent mode. If the watch is in silent mode, the alarm is only haptic and there's no sound. This is problem as many people use their Apple Watch in silent mode all the time - so in order to have alarm with sound you should take watch of silent mode each night and then turn silent mode back on in the morning that would be totally crazy. This is also confusing because on the iPhone alarms have been years independent from silent mode and now Apple Watch is working differently and also there's no mention in the UI that silent mode affect the type of the alarm.
I think Apple's implementation of wake up alarms is stupid and confusing. Because of this I got only haptic alarm this morning that is not enough to wake me up and I overslept and missed an important meeting.
If you think this is a problem please send feedback to Apple: https://www.apple.com/feedback/watch.html.
