Hi Folks,
I'm completely stumped on why I can't get values to return for this formula. It should return the first timestamp where an agent updated with a public comment:
IF
[Comment public] = TRUE and [Updater role] = "agent"
AND
DATE_FIRST_FIX([Update - Timestamp], [Updater role],[Comment public])
THEN
[Update - Timestamp]
ENDIF
This consistently returns no values, no matter what I do. Am I missing something here?
I even got it down to a single ticket with a clear correct date that should return, and it says there's no tickets. I have no filters that can be interfering: 
It's literally just a single ticket ID so that the results are nice and small. Why does this return no data when I add the custom attribute?
