Fairly new to Mixpanel. I'm curious if there's an easy way to set up cohorts defined by users' behavior within a certain time frame immediately after first use. For instance, how would I define a cohort with new users that did the Purchase Item event 3 times within the first week of use?
Every time I try to make a cohort like this, it seems I am limited to an absolute time frame (last 30 days, March 1 to March 29, etc), instead of a subjective time frame.
Any ideas? Thanks in advance!
