I am building batch audiences in AEP and the counts I am generating do not come close to the counts in Adobe Analytics that use the exact same evars/analytics. Why?

I feel your pain! Same issues here as well. The new UI release went active for us last week and it sounds like the same issues you're having persist.  They can give you access to a toggle button to go between the old and new while they fix the new. 

I agree. The new UI is very different and there doesn't seem to be a lot of good resources to help users learn how to navigate it. It would be nice to see a list of deprecated features and how to address the features in the new UI. 

Does anyone know what segment membership and the number below it means? I see this when I view sample profiles after creating segment rules using the rule canvas in Experience Platform.  

I am running an Experience Targeting activity with four different hero images based on customer industry. Does anyone know what the green star is indicating in this instance?
