Apple Limits Access to iWork for iCloud Beta Users
Last week Apple released the beta of iWork for iCloud to the general public and the response is so good that Apple is limiting access. The response to Numbers for iCloud beta is so “overwhelming” that some users need to check back and try again.
We've had an overwhelming response to Numbers for iCloud beta. Please check back soon.
In the meantime, you can continue to store your spreadsheets in iCloud.
Right now when I checked I was able to use Numbers without any message. This could just be because I’ve been using Numbers before people started getting this message. One thing that we can tell is that the public likes this new feature.
