Change iOS notification sound to be unique
Current iOS notification sound is annoying.
This really shouldn't have to be a Microsoft request, but for some insane reason, iOS doesn't let a person customize the alert sounds for an app.
I have appealed to Apple regarding this, but frankly have more faith in Microsoft making the adjustment than Apple at the moment.

The current notification sound is far too unobtrusive to be useful. We use this as a secure messaging system by phone, but cannot hear when messages come in.
