TL;DR
The arrow to the pinned object should show when hovering over it, even if it is set to not always show.What?
When a pin is set to "always show", the arrow and distance appears.When a pin is set not "always show", the arrow doesn't show. Hovering shows the camera at the pin, but there's no way to know where the pinned object is, requiring the player to edit the pin, enable "always show", get to the object, and disable "always show".
Hovering over the pin to show its direction and distance is more user friendly.
