My son was in a similar situation as your DS/DD for the Class of 2027. He applied to both the Naval Academy and West Point, and while he received two nominations to West Point, he didn't receive any to the Naval Academy. From January to April, he checked both portals daily and eventually received an offer from West Point. A few days later, he received an NAPS offer from the Naval Academy, which was perplexing because he never received a nomination for it.
In my opinion, if your portal is still pending this late in the game without a nomination. I believe that your DS/DD might receive a NAPS offer as well. The odds are in your favor. Good luck!
