Data Changes After a Lead Enters a Wait Step
Issue
You want to know if updated lead/person record data will reflect changes to that data made while the lead was in a wait step. This is important to know, because values could affect the following flow steps. For example, if there is a choice in the send email flow step that is determined by those values.
Solution
Any information that was updated while the lead was in the wait step will be reflected in the next step.
