Sounds like something got dropped on the floor. Usually, you do the training and request the background check, and 3 days later you get an email with your YPP certificate. (I'm not aware of any paper option other than printing it yourself. Chapter leaders would only see your YPP status if they do a lookup of your name and EAA number on the YPP web site.) It could be that they manually resubmitted the background check and the request didn't have your email address attached.
