My online registration showed "processing" until just before I checked in to my departing flight, at which point it was accepted, and I wasn't given any trouble at exit control, but according to some this will result in denial of future TWOV. I'm about to book another TWOV trip (the itinerary itself is compliant so I won't ask about that), so I figured I'd ask here if anyone has had experience with this kind of slip-up.
I've never heard of anyone being chastised for failing to register by the 24 mark (as long as they register at some point between then and their exit). Of course, if you end up in a police station situation while you're in this gray zone, you might be in a bit of hot water.
