I have a journey builder event which fires when there is a update in the lead object. The entry criteria is based on the values of multiselect picklist. The multiselect picklist values are A, B and C. Based on the value changes a new email must be triggered for each value. For example if some one adds A as new value then email related to A should be fired.
I have used the entry condition like field contains A or contains B or Contains C.
However the rule fires only when i completely remove the values from the field and add them again. Updating along with existing values not triggering email.
