When using 3D touch on iOS device the resulting menu items are not usable - these cannot be clicked manually or automatically:
The "Mark My Location", "Send My Location" and "Search Nearby" buttons are not usable.
3D touch in SpringBoard is known to be unstable, stemming from Apple's implementation.
This is a limitation that has no current workaround.
