So I’ve been playing around with the maps select feature from the main live map, and have found something interesting.
I did find that the created coordinates are actually saved but are not appearing immediately on the map.
If I change to the premium offline maps, or another map provider, the saved waypoints are visible. If I refresh the map using the Add More Geocache Waypoint button, next to the map select button, the geocaches are added, the visible map refreshed, but the saved waypoints are no longer visible.
If I change to another map—I was switching to Google and Apple Hybrid maps, and the premium offline maps—the saved waypoints are visible again, but disappear when I select the add more geocaches button.
Weird.
