letter i got after i get my AED the following day on an USCIS ennvelope, AED card mailed to me on a secured usps envelope not an USCIS envelope like on the letters

you see the priority date was blank, on my first letter it says "not this one" that what is in the priority date wouldnt be the right priority date based on the upcoming case result that is on going, something like that, it on my 797c notice of action for recieved payment, priority date there was when i paid for everthing. the following letters all leave blank, cant find that receipt letter but ill try to find it when i get home and picture that as well
