OK, I solved this. It’s a bit strange though.
I set the note.identifier to a string from a URL which is different for different elements in the app. But setting the identifier to anything at all seems to stop the whole thing from working. If I don’t set an identifier, then the notification center works as I wish and as it is designed. If I set the identifier, even if I set it to different values, the notification center a) never shows a banner, even though it’s set to do so and my delegate should be forcing it to show it, and b) it only ever lists one notification for my app. I verified that each identifier is indeed unique.
So simply not setting an identifier fixes the problem.
I thought I needed the identifier to figure out which notification the user activated, but I can do that using userInfo, so that’s fine.
Bit odd though.
