We have moved from App Measurement to WebSDK. When we were using the Application Measurement Code we had a synch call within Launch when the user logged into our site and we set that value to the eVar where we capture the hashed loyalty id.
I am not finding documentation on how to do a synch call or what to configure in AAM to get a synch call working.
