Sometimes tickets may overlap exactly, making it difficult to select a specific ticket.
A ticket's pin may be moved by clicking the Move Pin button and then clicking or tapping within the location map where the pin should be moved to. Once the pin has been placed in the desired new spot, tape or click the Save button to make the move permanent.
Here is the step by step process:
In the example there are three pins overlapping.
Tap on the top-most ticket pin. switch to location tab. 'move pin' etc.
The Map view will show the top ticket's pin in the new location, exposing the other ticket's pin for selection.
