Locations won't synchronize

WEB iOS

Occasionally you may find certain saved locations appear not to synchronize across devices or between the Photo Ephemeris Web and the iOS apps. This is typically due to differences in computer clock timings between devices.

Here are some simple steps to try to solve this issue.

Make a backup

Firstly, create a backup of your saved locations on each affected device and keep in a safe place. You shouldn't need these, but it's always best to have a backup at hand.

For Photo Ephemeris Web, this is done as follows:

See this post for details on exporting from TPE for iOS, and this post for TPE for Android.

Synchronize locations on each device

Next, for each affected device, synchronize locations using the synchronize button on the locations page in either TPE for iOS or the Photo Ephemeris Web. Synchronization happens automatically on Photo Ephemeris Web, but may still be triggered manually.

This will ensure that your locations are at least synced to the server. You should verify that each location has been synced to the server by checking for the presence of a cloud icon next to the location:

Clean your locations

Cleaning locations removes locations from the local device but not from the server. It also resets the "last synced" date/time. Signing out of your account automatically completes this process. But you can also complete it manually on iOS as described below.

Note: On TPE for iOS, cleaning locations does not delete anything on the device that was not already synced to the server. This does not apply to the web app.

For Photo Ephemeris Web, you can clean locations as shown:

In TPE for iOS, go to Settings, scroll down to the Locations section and choose Clear synchronized data…:

Re-synchronize on each device

Finally, on each device Synchronize locations. This should resolve the issue and all locations should appear on all devices.

Still having trouble?

If you're still having trouble, please open a support request. Be sure to include specific examples of locations that are missing from your device or are out of date so we can check them on the server in the first instance.

Screenshots are always very helpful in troubleshooting, so also include those if possible.
