Creating a report of User longevity

Get Help
1

I have a field "Last Activity" on the site and another field account "Created". I read in Metabase documentation that I can use the function "datetimeDiff" to calculate the difference here: DatetimeDiff

I tried this function by using the following equation as either a custom column or a custom expression:
datetimeDiff([Core User - User → Created] , [Last Activity] , month)

And I receive an error: "Unknown function datetimeDiff"

What do I need to add or change to use the datetimeDiff function?

Can you share Admin -> Troubleshooting -> Diagnostic Info

That function worked on the 45 release ... I am afraid you are not on release 45

You are on the 44.6 which still doesn't have that function.

Also I noticed you are a customer of metabase (1.44.6), then you can go to Admin > Troubleshooting > Help > click "Contact support".
