Past tracks and waypoints are gone from iPhone.

Over the past few years all tracks and waypoints I entered into the iPhone app were visible and also downloaded to gaiagps.com.

Yesterday I recorded a new track and entered waypoints, but they did not appear on the iPhone App. But they were downloaded to the website. The website shows all past tracks, waypoints, including the one I did yesterday.

I have synced the app, but still the tracks (new and old) do not appear.

Thanks!

Jim
