Is that new? Was instant for me in the past.
Was for me as well, but recently had a few friends that said it took a few days and when I tried last [1 week ago] a larger amount, it took 2 days.
I called Hyatt and they said its not on their side but also said it can take 7 days.. , Chase shows as processing.
It's possible it has to do with new accounts or large amounts, but multiple reports of waiting longer then instant justifies the removel of the the "instant" label.
