Is there a way to recall an Amazon (or other) notification, on iOS?

I tapped on a sale notification from Amazon, but the amazon app on my iphone stalled today. There was a discount code in the notification, but I can’t get to it now, because the app isn’t loading and the notification is gone. Is there a way to recall or review notifications that are no longer visible?

Contact amazon. Your account history is visible to account reps. (I’m on the chat now with them because an earlier promised $5 credit is not appearing in my cart during checkout)
