I tried to update existing issues and create new issues via CSV import.
[Purpose of CSV import]
1. Update 2 existing issues --> update attribute of issue (e.g. due date, status )
2. Create 2 new issues
The result was failed.
Only new issues were created but existing issue was not updated.
How to update existing issue via CSV import?
Below is detail log of importing CSV files
