The Trailforks app contains an offline database of every trail and region in the world for offline searching. If your search database has become corrupted for some reason, you can clear and re-download the entire search database:
You can fix by going to your:
- App Settings -> Manual Sync -> Update Search
- Choose "Clear and reload"
This will force the re-downloading of your entire search database. This might take some time as this data is 150-200 MB. After the re-download is completed is done, your app will only sync small updates, and your search database should be restored to normal.
