Aulani Passholder Discount with Expired Disneyland Pass

[mel2014]

We had Disneyland Flexpasses that were paid in full and didn't request a refund. Our passes "expired" 11/8 and have now disappeared from the app/website. We are looking at possibly booking a stay at the Aulani in February and would like to take advantage of the passholder discount (which includes a $50/night resort credit above and beyond the non-passholder discount currently being offered). Does anyone have any recent experience trying to get the AP discount at the Aulani with an "expired" pass?
