notification management on iOS is just different than on Android. It is a bit more hands off. Most recent notifications appear in your face and then they fall into the 'notification drawer' unless you take action on them, in which case they disappear. Once you adjust to it not behaving the same as Android, you get used to it.

On my android device, I never had many notifications as I would manage them and clear them. On iOS, I tend to clear them once a week, and the thought of returning to Android's notification system just seems like a lot of work.
