I tried the link in the wiki for 80k and $50 statement credit. I was redirected to the 60k landing page.

I logged into IHG and searched for reservations to see what credit offers I would receive. After clicking Check Rates, you would see what is being offered to you.

First I received the offer for 60k and $50 statement credit.

Went incognito mode and tried again. I saw the 80k and $50 statement credit. Click on the link and it took me to the landing page. Clicked Apply Now and it took me to the application page with no redirection to the 60k offer. I just applied and got approved.

It'll take you to the offer with the code FGKL, same as the wiki. If it works, it'll take you to the page where the offer code is 6ZZN. I did some more testing, it seems you have to be logged into IHG, make a reservation, click on the link from the bottom of the page after checking rates, then click apply. Information on first page of the app is pre-populated from your IHG account.
