I did the same thing for my appeal. I did get he same response and spoke with a VA rep and finally case is under the claims column vice the appeals column in E-benefits. It has been moving back in forth from "reviewing evidence to Prep for decision" . It is recently in the Prep for decision column as of this AM. Of note, when I went under the RAMP appeal system, VA sent me out for another C &P exam (weird in itself) and I am told that I do have sleep Apnea and that the DOC during the C&P agreed it was attributed to my mil service. . Now, I was already at 91 points, so , I am hoping this decision whenever it happens will get me to 100%. I have been dealing with the VA for 15 long years! Sooooo tired.
The only advice I can give is to hang in there and they will get to your case much sooner that the DRO review.
