If waypoints are not displaying on the map in the app:
1. Ensure the Waypoints overlay is toggled on with these steps: Show or Hide Saved Data on the Map.
2. If the waypoints are in a folder, make sure the folder visibility is on. See the link above to turn the folder visibility on.
3. If the waypoints were added while recording a track, they are associated with that track and they will only display when that track is set to display on. See the link above to turn the track visibility on.
