请问下有小伙伴收到We are still reviewing your case的邮件吗？

坐标美东，今天早上收到uscis的邮件说：We are still reviewing your case and there are no updates at this time. We will notify you when your case status changes. We last took action on your case on April 23, 2019. 但是我刚查my.uscis的状态依旧停留在04/19/2019 Case Was Received，所以比较迷惑，请问是哪里能查到更新的状态吗？在uscis官网查还是Validation Error(s).谢谢各位了！祝各位都有好运！
