Ok, now it's getting ridiculous. When making a map, not only the latest trivia is saved, but all my intermediate saves are saved as well. And now users can see all my edits, including doublets, spelling mistakes etc.
I now have this map with 1.700 locations, https://www.geoguessr.com/maps/67312166c22a8c3d28e82cce, that contain trivia for each location. But no option to delete any trivia that is invalid. I can only see the latest trivia.
So in essence, we need a feature to delete any trivia that we created ourselves, leaving only the correct one behind.
Not that I'm looking forward to going through all 1.700 locations to clean up trivia textx. Sigh...
