Troubleshooting steps

Most iCloud Sync problems can usually be solved by the following steps, run through them in order until syncing continues as expected. After each step, give it a try, if it's working, no need to keep going!

Please also ensure you always have a backup of your data. See this page for our recommended Back-Up Methods.

1. Wait 15 Minutes

iCloud is optimized to efficiently transfer data, and this can mean updating once an hour if the network connection is weak, or the battery is low. Syncing can be as quick as a few seconds on a strong internet connection, but a few minutes is very normal.

2. On an iPhone or iPad: Check the following settings in the iCloud section of the Settings app on your device. Go to  Settings > Apple ID > iCloud

  • Check that all devices are signed in to iCloud with the same Apple ID. Data cannot sync across multiple iCloud accounts. 
  • Ensure that iCloud Drive is ON.
  • Ensure LogTen Pro is ON. 

3. On a Mac: Check the following iCloud settings in System Preferences > Apple ID > iCloud

  • Data cannot sync across multiple iCloud accounts. Check that all devices are signed in to iCloud with the same Apple ID.
  • Ensure that iCloud Drive is enabled.
  • Click Options next to iCloud Drive, and ensure that LogTen Pro is selected.

4. Enable Cellular Data

On iOS, if you wish to allow syncing on a cellular network you must allow LogTen Pro to use Cellular data. To do this, go to your devices Settings app then Cellular. Scroll down to LogTen Pro and select it ON.

5. On a Mac or iOS try a hard reset of the device

A hard reset will restart the system process which can fix iCloud Sync issues.

6. Make sure you are running the latest version of iOS on your iPhone or iPad, and OS X on your Mac

System updates often contain fixes and improvements for iCloud issues. For details and directions see Updating iOS & Updating OS X

7. Make sure that you have adequate storage space on both your device and in iCloud.

8. Add an Empty Flight to each app

Occasionally iCloud encounters a problem uploading a file, preventing the other apps from processing further changes from a device. The process of creating a new entry will ensure that database is saved, and the changes will prompt iCloud to re-attempt the failed upload.

9. Check Apple Services Status for any iCloud outages

If there are any iCloud problems reported, try again later.

10. Restart iCloud

 Often restarting your iCloud will work. See this article for instructions: Restart iCloud Sync

 

Common iCloud Sync Problems

“Please Enable iCloud” even though iCloud is turned on OS X 10.10 or later.

iCloud Drive must be enabled on all of your devices to sync using iCloud. If you are using a work-provided device it is possible iCloud Drive has been disabled. If you are using an older Operating System you might not have iCloud Drive. iCloud Drive was introduced after  such as iOS 8 and   OS X 10.10 Yosemite,

“Confirm Your Subscription/Coradine Account”

Your app may need the subscription restored or you may need to be logged into your Coradine account. To learn how to create an account, please see this page: Creating a Coradine Account. To restore your purchase, you'll need to be logged into your Coradine account then go to Settings/Preferences >> Store and hit the "Restore Purchase" button.

For Mac users, the Coradine Account was added in version 7.4. If you have recently updated you will need to follow the steps in the link above

"Unable to Start iCloud Sync" after multiple attempts

If the message says "An error occurred while validating your logbook with the existing data in iCloud..." there may be a small error in your logbook due to an incompletely removed entry. please Contact Support from the Help tab to have this issue corrected.

Stuck at "Merging with logbook in iCloud..."

Depending on your logbook size, this process usually takes just a couple minutes but it may be closer to 15 minutes if you are starting iCloud for multiple devices that have large logbooks. Even if you previously used WiFi Sync with them, the full sync is required to verify all entries.

"Ready for iCloud!" appeared, but the data from the logbook doesn't appear on my other devices.

Wait at least 15 minutes. The data added to iCloud needs to be uploaded to iCloud, then your other devices need to wait for iCloud to deliver the changes, and finally, process them.

 

Using Firewalls or Anti-Virus Software

If you use a firewall utility or anti-virus software on your Mac, please ensure that the “UBD” process is able to access any requested addresses. UBD is the system service that handles the movement of iCloud data and blocking it will prevent iCloud Sync from working properly in LogTen Pro and potentially all other apps that use iCloud.

Utilities may try and block the following from being accessed, but we strongly advise you to allow UBD to access whichever services it requires, as Apple may add new capabilities (or use new addresses) for iCloud in the future:

  • Allow any connection to domain apple.com
  • Allow any connection to domain icloud.com
  • Allow port 80 and 443 for UBD
  • Allow port 80 for domain amazonaws.com

Any app that uses iCloud relies on iOS and macOS to sync your data between your devices and iCloud itself. If macOS or iOS encounters any problems while syncing then it may prevent changes being synced between your devices.
