I called the Hilton help desk and the person who I spoke with couldn't find the promotion on her end as associated with my account.

She's going to alert the IT folks that the "popup" approach for the Just One Stay promotion is hit or miss from a technology perspective.

I was offered a modest amount of points (1,000) for my troubles and declined the kind offer as I'm more interested in actually staying at a Hilton property (and getting out of the house.) Things can't get fixed if the IT folks aren't aware that it doesn't work.
