Apple has begun limiting access to the iWork for iCloud beta for some users due to an "overhwhelming response", notes 9to5Mac. The company launched the beta to developers at its Worldwide Developers Conference in June before starting to invite non-developers in batches last month. Apple opened up access for all users last Friday, with that influx apparently pushing the service's current limits.Sorry 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.
