How to find total users that are still using an older version?

Hey @Bill 

If I’m understanding your use case correctly, then you can use the most recently clause on your version property when defining your cohort. This will select only users whose most recent value for the property matches the value you've specified. This value will be drawn from a user's most recent active event.

You can then create three different cohorts specifying the relevant version numbers and the most recently clause. You can either use since June 5th or Last X days accordingly .

One caveat which can occur is that user can update to v3 and never send any other event after that. If you don’t have any event capturing this version change property, then this user will be included in the cohort for the version property of their last sent event ( let’s say in v2 )

Hope this helps.
