I recently flew on united hnl-gum since last trying to get the offer to show. maybe that helped. I used a chrome browser on private mode. . then signed into my united account. then clicked on business products under products and services. then the MileagePlus Explorer Business Card link. at first the offer showed 30k. clicked on the club card, which showed $395 fee waived the first year. clicked back to the MileagePlus Explorer Business Card tab, and then it showed the 50k offer with 2k spend.
