I saw this question posted earlier but the suggested answer doesn't actually answer the question. That answer seemed to explain how to find a specific value.
I am, however, wanting to write a script to show issues that have more than one value selected in a multi-select field.
Use case: we have a Program Increment field on epics. This field is multi-select so we can report on epics that take more than one PI to complete. I want to run a script to show me epics where more than one option is selected in the Program Increment multi-select field.
