Where’s my iOS 11 update. – PITFALL!™ Review

Just updated my iPhone and it says I can’t play Pitfall because it doesn’t jive with the new OS. (We’ll, actually, the iPhone doesn’t SAY I can’t play it because the iPhone is incapable of speech but I did get a message to that effect.) Any word on an update?
