I won't really be able to help much. All I know is that after we got our first couple of Chase cards the ability to transfer online was not working (I think for anyone, according to these forums), so we had to call in to have the points transferred...which worked no problem. I think the process had always been that the first time a transfer was done it had to be over the phone, but subsequent would work online.
Anyway, all of a sudden about a month ago, I was looking at SOs account and saw the option to transfer URs from SOs Chase Saph Pref to my Chase Ink Pref...so I did it.
The only thing which is probably WAI is that when I go look at the accounts now, I can't see anything;...but that's because if there are no Chase points available then there's no option to transfer (which makes sense).
