I just unsubscribed from Marvel Unlimited (and deleted the app) because they don't provide any mechanism for disabling marketing notifications ("Here's an issue of something you've never read!") vs. functional notifications ("Here's an issue of something you've starred!") vs. transactional notifications ("Your subscription is coming up for renewal!"). I understand that, for some people, new issue notifications are a plus, but not giving us a chance to filter out that noise is abusive. It's my phone not your billboard. Anyway, thanks to this thread I went back and checked my notifications settings and a surprising number of them were set not only to allow immediate notifications, but also to "announce" their notifications. Turned all those off.
