In Opsgenie on a latest updated iOS iPhone, when I go to Profile -> Sounds and try to select a sound other than iOS Default Ringtone it will not play the select sound. Even if I go back into this setting and select the sound again, it remains silent.
If I select iOS Default Ringtone I hear the sound, even if I press it multiple times I hear it, if I select any other sound and even selecting it multiple times I do not hear in in this setting.
So I am left unable to select another sound as I am not sure it will play if I receive an alert?
