As of 12 hours after the release I still have received no discount email.
I checked your orders, and from the email you are using on the forum, it seems you bought a copy of O'Hare 2011 sometime in 2016, then you bought a *second* copy of O'Hare 2011 in August 2019, just after O'Hare V2 was released, which seems like a mistake.
Haven't you realized to this day you were still using the old version ? Sure, it can be installed in P3D, but it's still the same old version from FSX with the old runways, and looks completely different!
This explains why you haven't got an email with the offer, which is reserved to people that bought O'Hare V2.
In any case, I guess you buying two copies of O'Hare 2011 can reasonably qualify for a discount offer on O'Hare MSFS, so I manually sent you an upgrade offer now. I'd guess you'll finally be able to see the real O'Hare V2!
