How do apps like Alarmy or Wakey do this without using critical alerts?

does it have to be a .caf file, or a certain duration sound file? mine is a .wav file.

I’ll keep trying but so far none of the suggestions have fixed the issues :( I can’t figure out from the documentation

I’ve tried using your suggestion even on beta 4 and I still can’t get the custom sound to play.

I haven’t solved the issue yet. Even with beta 4 custom sounds aren’t working.
