No sound from iPhone bedtime alarm app

This is so frustrating to see how Apple is not even caring about one of the critical bug.

When I wake up, I see bedtime display with NO SOUND!

Alarm/bedtime is supposed to make SOUND.

At times I have doubted myself. But after reading some threads, I'm sure that my ears are fine.

Also, in the bedtime Options, there are not many good sounds. All are very low in volume. However, in vibrations, I see a ton of options along with "Create New Vibration"!!. Who is the product manager for this? You are trying to construct a fine building without a basement.!

I would be really happy if this bedtime never works. I would've used some other phone for the alarm. But sometimes it works. That the problem of uncertainty. First, fix this random bug and then add more sounds. Later you can let kids create custom vibrations!
