I flagged an answer as "not an answer". The flag is currently "disputed", and after a second look, I realize my initial flag was in error. However, I'm not able to find a way to retract the flag.
As I understand it, I should be able to click the 'flag' link again, and a "retract" button will appear in the dialog. However, there is no such button.
Am I doing something wrong? Does the feature not apply to MP&T? Are there conditions where a flag cannot be retracted? Something else?
