New H4 EAD application: "Attn H4" missing

I applied for new H4 EAD for my wife. However while sending documents USPS person forgot to add “Attn:H4” in the address. So on my package ‘to address’ was just USCIS, P.O. Box 20400 , Phoenix, AZ 85036. How will not having Attn:H4 on my application impact my EAD processing. I submitted documents on 17th March 2021. USCIS received them on 18th March but I have not received any receipt notice yet. Thanks in advance!
