Unable to move map marker to precise location

After selecting pickup / drop location, I am unable to move the map marker to the precise location I want to be pickup up / dropped off. Marker seems fixed and moves with the map that too on _two finger scroll_.

Start by locating the pickup and drop-location map interaction in the Kotlin application and reproduce the marker behavior described in the issue. Trace how the marker responds to one- and two-finger gestures; done means the user can move it independently to a precise pickup or drop-off location.
