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 individual track is marked as visible. See the link above to turn on the visibility for the individual track(s).
