iOS Facebook notifications

The iOS Facebook app stores its settings on the cloud. This is annoying because, logged in as I am on both my iPad and iPhone, I can’t turn notifications off for just one device; I will always get either two buzzes, one from each device, or none.

I know, first world problems, right?

Nonetheless, my general question: how can I disable notifications from the iOS Facebook app on one, and ONLY one, of my iOS devices?

Can’t you change notifications in Settings? Or do they affect both devices?
