iCloud pages won't load on any web browse…

I am having this same issue on iMac with my business Apple ID: Pages for iCloud.com just spins and spins and says "Loading" but never loads. It happens on multiple iMacs, and on multiple ISPs. There is over 4GB of available storage space on the account, and the Pages documents can still be accessed through iCloud.com's iCloud Drive.

I discovered that it is not a problem on every iCloud.com account, because I can log in with my personal Apple ID, and iCloud.com Pages loads fine. The big difference between the accounts is that the business account has over 150 Pages documents in it.

My guess is that there's either some sort of limit to the number of documents, or there is a corrupt file in there mucking things up. I'm experimenting to see if removing files fixes the problem.
