Go to your settings page and check "Automatically build My Finds GPX files" and click the "Update settings" button at the bottom of the page. After a day or so, you will find a GPX file with your finds at the bottom of the Job Queue page.
I checked "Automatically build My Finds GPX files" but I didn't see the button "Update settings"
So I waited five days and no GPX file of my finds is generated.
What can I do?
