I am also seeing the same issue whereas tapping "Keep" does not ask the user if they want them delivered prominently or quietly. It does have a button asking for showing them in a summary - but I as a user do not have summaries turned on. Tapping the summary button does not enable summaries either. I am trying to convince people we should switch over of using "provisional" notifications to be better iOS clients, but this issue will never get past the product department's scrutiny.
