A. This is usually the result of not having enough data to calculate correctly.
If you have a cohort which is created with an 'in session' clause, Permutive will be unable to calculate the audience size. However, once you have set up the cohort, you can see its growth in the analytics reports. After 30 days you will have enough data to report for an RFP response.
To receive an up to date estimate, the estimator will need to be re-calculated by manually pressing the 'Calculate' button at the bottom of your cohort builder.
