iCloud Synchronization Failed - Help!

If you are using the Full version of iPIM™ and have enabled iCloud synchronization on your iOS devices, you may - on very rare occasions - find out that some items do not synchronize, or that the initial synchronization fails.

iCloud synchronization is a very complex process. It is handled by the Operating System (iOS), not by iPIM™. Network errors or timing issues may cause it to fail, and although it's very rare - it can be frustrating.

If this happens to you, here is what you should do to restore normal synchronization - but only if you're using iOS 7 or above and the latest version of iPIM™ (DO NOT try this on older iOS or iPIM™ versions):

  • Disable iCloud synchronization in iPIM™ on all devices.
  • Delete iPIM™'s data from iCloud, using the iCloud option in your device's Settings application:
    • Start the Settings application on one of your devices.
    • Go to iCloud, Storage & Backup, Manage Storage, iPIM.
    • Select the Edit option at the top of the screen.
    • Select "Delete All".
  • Wait for at least an hour.
  • Re-enable iCloud synchronization on your main device only (the device that has the most updated data). You should see a delay and then a prompt asking you whether this is the main device or a secondary device. Select "Main". If instead you'll see a prompt telling you that this is a secondary device and its data will be erased (without asking you if it's the main device) - cancel the prompt and wait some more.
  • Wait for at least another hour.
  • Re-enable iCloud synchronization on your other devices, one at a time, waiting for at least one hour between devices.

This will copy your data from your main device to your other device and restore iCloud synchronization, but please note that the process may take a long time, depending on the volume of your data and on network condition.
