Does the online oyster history ever work?

IIRC, it says someone like it only works if you have purchased pay as
you go credit from Oyster online. So, I did that on Friday and got
the card updated on Saturday. Still no online history for Saturday or
Sunday. It shows the correct balence, just no history. I need this
for my expense reports.

And has anyone pointed out how un-tourist friendly the website is? In
order to register my card, I had to make up a Postcode because it would
not accept my valid US Zipcode.
