Not seeing my iWork documents on iCloud.com

Hi all,

I have created some Pages documents on my iOS device (iPad "3" running iOS 6 Beta) with iCloud storage turned on, but when I go to www.icloud.com/iwork no documents are showing and instead it's asking me to install the iWork applications.

Note that this also happened with iOS 5.1, so it's not related to the use of the beta version.

Does anyone have any clues to to why this would happen?

Thanks in advance,

Lucien.
