I just received my rating for PTSD an on ebenefits its says service connected with an effective date of 06/11/2018, but when I go to va.gov an print the letter out it says "The effective date of the last change to your current award was: 12/19/2019. I filed this claim on 01/15/2019. I'm a little confused on which one will be my effective date concerning back pay.
