i haven't read the entire thread so i'm not sure if this is new but i tried to add my wife to my account and got the unexpected error. i tried adding me to my wife's account and was able to do so and was able to transfer points. i have a sapphire preferred but my wife has a reserve so we would like all the points in her account. i sent a message to chase and they supposedly forwarded my request to the correct department but we'll see what happens.
