As reported a few pages back, I am part of the group that does not get any audible alerts on my phone for emails. Works fine on my watch and mac. All settings are 100% correct, including the customize options. I reported this back in September, which Apple acknowledged. That said, I have other iPhone users on my account who all have the same issue. Curious if this could potentially be a carrier thing given the randomness of who it works for and doesn’t work for? Perhaps something to do with intelligence settings? There doesn’t seem to be any rhyme or reason.
Also, text message alerts are also random. Sometimes light up the screen and/or alert, other times I get nothing.
