I can't access Pages(beta) on iCloud.

Same issue. Pages on iPad is not synching with iCloud. When I log into iCould, I get the loop as well. Same for Keynote and Numbers.

When I open my iWork apps using my Macbook Air and click on iCloud, I also cannot download and view my documents. It just has "waiting" status and nothing happens.

My wife's account doesn't have this problem, though...

Having the EXACT same issue, called Apple Support and they escalated it to get help from the iCloud engineers.

There is a longer thread about this issue, and a developer has reported a similar issue to Apple.

I called them and they are aware of the problem. It is not on your end. What is really lousy is that this is no minor glitch. iCloud is effectively not working for all iworks users so you would think the apple would notice folks with icloud accounts. Apple does not do that. Bad publicity bad for sales. So users spend time trying to figure out if the problem is on their end. They had to bump me up to a senior person before acknowledging they had a problem. If I called my cable company even the lowest level tech would be aware of the problem.

Not true. I think it is a minority, and that is why they are somewhat slow getting to it. I and many others have had no problem (yet).

Interesting, I wonder if it is only effecting one region or certain accounts. I know that I am not the only one experiencing the problem as reflecting in message board comments.

My docs are now properly syncing between devoces, I can view them on icloud.com, and my ubiquity.log no longer shows my account as locked.

No e-mail or phone call from Apple.
