Why do people even care about the Palladium card anymore? It's now a strictly worse earning card - before it made sense if you spent $100k per year on solely travel, now it absolutely does not. If your Palladium AF isn't waived, why keep it?
I'm a JPM PB client and never bothered with the Palladium card but just applied for and received my JPMR card since it's clearly worth it. Already have UC through my MileagePlus Club card so not going to be a guinea pig for non Palladium card holders getting complimentary UC with the new card.
