No good anymore

I used to us this app and depend on it regularly. I have now slept in too many times- as others have mentioned, the alarm does not go off. I have done everything, too, in my settings/notifications- but the darn alarm does not work in a locked screen where it always used to. I can no longer depend on it - very frustrating and disappointing....
