Q: all my files just disappeared from my pages and numbers apps on my mini iPad. Under Usage, both still show 350 MBs used for each. Ideas?

Hello r253,

The following troubleshooting steps can help get your documents to reappear on your devices.

Documents I've updated on my Mac or uploaded from iCloud.com don't appear on my iOS device

1. If you're using an iWork for iOS app (Pages, Numbers, or Keynote), check the iCloud system requirements and make sure that you're using the latest version of iWork. For third party apps, check the documentation that came with the app, or check with the app developer to make sure the app supports iCloud. App Store application descriptions often indicate whether the app supports iCloud.
2. Go to Apple () menu > System Preferences on your Mac. Click iCloud and confirm that you're signed in to iCloud and the Documents & Data checkbox is selected.
3. After opening your iOS app, wait a few minutes for the documents to appear. Your iOS device may not have connected to iCloud since changes were made to the document at iCloud.com or on your other devices.
4. Try creating a new document on your iOS device, then check again for the documents from iCloud to appear.
5. Go to Settings > iCloud > Documents & Data and confirm that Use Cellular Data is turned on.
6. Confirm that you're connected to the Internet by checking for an Edge, 3G, 4G, LTE, or Wi-Fi icon in your device's status bar. Test your connection by opening apple.com in Safari.
7. Try resetting iCloud Documents & Data service.
