WaniKani for iOS

Hi kiko,
I have a problem, the push notification feature does not work for me. Though, there is a badge but it only updates when I open the app. That’s why I have to make my own notifier(/t/WaniKani-Email-Notifier-Never-miss-your-waiting-reviews/4140/1). I saw you mention push notification on the first page so it may be only me who have this problem.
