Important App Update Coming

5 June, 2025

Hi ExplorOz Reader

We’ve got a very important TRAVELLER app update coming soon that will affect ALL users, and we want to make sure you're ready. Plus - if you've previously been a test user, please urgently scroll down to the timing section to check what to do immediately.

What’s Changing?

We’re about to release version 9.4.0 of the Traveller app to fix a critical and increasingly common issue with Trek syncing. This update introduces a completely new routing system and data storage method, meaning the old and new Trek systems are not compatible.

Here’s What You Need to Know:

As part of the update, the existing Trek database structures will be flagged as requiring download/sync.
After the update, your existing Treks will not work correctly until the content sync completes.
The content sync should start automatically the next time you open the app while online and will typically complete within 5 minutes or less.
This means you will need to have at least a brief moment of internet connection — for example, passing through a town, or using a friend’s Starlink — to allow the sync to complete.
We are coding this update with full respect and care for those currently travelling, to keep any disruption very limited.

Already Affected by Trek Issues?

If you’ve already experienced corrupted Treks, please note that this update will not fix them — those Treks will still need to be deleted and recreated.

This update is designed to prevent the issue from occurring in future, and we’re confident the new system resolves the root cause. If any problems do arise after updating, we hope you’ll work with us to report them so we can continue refining the system.

Offline Travel / Update Considerations

If you rely on Treks and expect to be offline during your upcoming travel, please prepare to get any brief online access soon after the update to allow the sync to complete.

If this won’t be possible, you may choose to temporarily disable auto app updates to delay receiving the update. Here’s how to do that:

On Apple devices: Open the App Store, tap your profile icon, go to Settings, and turn off App Updates.
On Android devices: Open the Google Play Store, tap your profile icon, go to Settings > Network Preferences > Auto-update apps, and choose Don’t auto-update apps.
Windows devices: Open the Microsoft Store, click your profile icon (top right), go to App settings, and turn off App updates.

Note: Disabling access to this app update is not recommended and may still not protect you from future Trek issues which could occur during your trip. The current version is increasingly causing issues, including:

Treks not appearing on the map
Corruption of Treks after saving

Device Compatibility

Treks created in version 9.4.0 won’t work in older versions, so ensure you update all devices to avoid compatibility issues.
The web app will also automatically update to version 9.4.0 once fully tested. Any Treks created in the web app at that version will not sync with older app versions, so updating all your devices is essential.
This update will also roll out to Windows via the Microsoft Store, so Windows users need to update too.

Timing

We’re releasing the beta version of 9.4.0 today for a short 24–48 hour test. The public release will follow shortly after — likely between this weekend and early next week, depending on the app stores approval and release schedules which can vary between stores.

IMPORTANT FOR TEST USERS

If you’re currently enrolled in our Apple TestFlight or Google Play Beta programs and do not wish to receive this imminent update, please urgently remove yourself from the beta program now to avoid being automatically upgraded.

Looking Ahead

Personal Trek Sharing is planned for rollout in version 9.5, which will complete the Trek update project.
Version 10 is coming later this year and will introduce the new map engine. Please note that the new map engine will not be supported in the Microsoft Windows Store version of the app but will be available in the web app.

Thanks as always for your support – we know Trek planning is a much-loved feature and we’ve worked hard to deliver a fix that brings long-term stability and reliability going forward.
