Geographical maps - Links are not showing?

I’ve added GPS coordinates to a bunch of equipment in the equipment and they correctly show up on the Geographical / World Maps section. However links between them are not shown?

I have verified in Settings → Web UI → World Map Settings that ‘Display network links on the map’ is turned on (and have tried toggling it on and off)

LibreNMS can correctly determine neighbor adjacency as the ‘Network Map’ is dynamically populated showing all interconnected routers and their links to each other. However Geographical / World map only shows the device icon at the coordinates, but no links between them

validate.php is not returning any errors

Any ideas? This would be immensely useful to have a dynamically populated geographical map but its never worked for me. Unsure how to troubleshoot this any further

Anyone else have geographical links working? If it’s something wrong in our deployment i’m able to rebuild it from scratch but i’d like to know if its actually working at all for anyone else, or if its a completely broken feature
